Description: The Ultimate Guide to Waterproof Dry Bags Dry bags are a must-have piece of gear for any outdoor adventurer. While they are simple, easy to use, you’ll find there are many different styles, sizes, materials, and features that go into them. I hope to guide you through the decision-making process with this ultimate guide to waterproof dry bags. Let’s get started! If you’re just looking for our best dry bag recommendation, check out Gold Coast gear for all sizes and colors. What’s a Waterproof Dry Bag? As the name implies, their primary job is to keep any piece of outdoor gear dry. The bag is a flexible container, typically with a roll-top closure. Roll-top Dry Bags provide a Watertight enclosure by the way they are secured. Instead of a Zip-top or zipper type of closing mechanism, the bag is secured by rolling down or dog-earing the top at least three times, them clipping the buckles together. We will go over other ways of securing a dry bag, but the most reliable ones are closed with a roll-top seal. The reason Mountaineers prefer this over a zipper and zip-top closing style is that a rolling top is virtually indestructible. Two pieces of fabric being pressed together won’t wear out like a waterproof zipper. It will perform the same in a cold environment (unlike a zipper) and can easily be closed with gloves on. Who Uses Dry Bags & What Are They For Waterproof dry bags are one of the most common items for many outdoor activities. It’s easy to see why, over the years, many people have adopted them. Backpackers: Wanting to separate valuable gear keeping it clean and dry. Have multiple smaller dry bags of different colors help keep them organized. Water Sports: It’s ubiquitous to find a large waterproof dry bag on a Kayak or Canoe. Waterproof backpacks are used for paddleboarding or SUP for short. Large dry bags are also routinely used for rafting as well. Camping: Dry bags are used to keep wet gear separate from dry clothes. Small dry bags can hold electronics, keeping them safe from water and dust. Alternative Uses: Using them as a pillow, gathering water, a bear bag, and a boat anchor. These are just some of the uses for people that need to protect their equipment. Different Closing Dry Bag Styles Closing roll-top dry bags is recommended, but let’s look at other ways of closing them. Let’s compare the zip-top and zipper closing bags to the roll-top. Zip-Top or Ziploc Closing Dry Bag This type of bag is excellent for smaller, lighter items that fit nicely in the small pockets of a backpack. I keep a few Ziploc bags whenever I go hiking to keep my toiletries clean. The problem with this closing mechanism is when you have larger, more substantial items. With heavier gear rolling around in a Ziploc bag, the top can easily blow out. If you close a Ziploc bag with air in it, a small amount of pressure will pop the bag right open. A roll-top dry bag won’t do this. If enough force is applied to a roll-top style bag, the seams will blow out before the top will. Cold weather will make the zip-top stiff and hard to close. While they will be fine in most temperatures the cold weather will affect the performance. Freegrace sells a dry bag that has a zip-top combined with a roll-top. While this isn’t necessary or really adds any extra protection, they claim it’s for added security. They also note that in cold weather, the zip-top won’t perform well, and oil needs to be applied before closing the bag. Waterproof Zipper Dry Bags A true waterproof zipper will not leak, but the problem is many so-called “Waterproof Zippers” are merely water-resistant. This kind of zipper will let water leak in if they are exposed in the rain or dropped in water long enough. Bag manufacturers do this to save on costs because true waterproof zippers are expensive. Another downside is that waterproof zippers are stiff, so they don’t slide easily like the normal zippers we’re used to using. This can be a real pain in cold weather as the zippers will be even stiffer. Lubricating the zipper can help with this stiffness. As with zip-top bags, zippers can blow out when overstuffed. If this happens while you’re out on the trail, you could be stuck with a useless bag for days. The last downside is that zipper bags are difficult to close with gloves on. In cold weather, the zipper will stiffen up, making it even hard to close with thick winter gloves. How to Choose The Best Dry Bag Before we look at different sizes of dry bags, we need to choose a material first. Dry bags generally come in two different categories, thick heavyweight or thin ultra-lightweight material. Thick Dry Bags Some dry bags are heavy, but they’re built to take a beating. Take a look at a dry bag made from 500D PCV Tarpaulin for durability. It’s tough, but at the downside of being very heavy and inflexible. These kinds of dry bags are usually recommended as “best value” because they last for years in harsh conditions. Benefits Of Having A Waterproof Backpack One of the most infuriating things about going camping, backpacking, or hiking during the rainy months of the year is reaching your destination and finding all your gear and equipment soaked through. And it doesn’t even have to be raining for you to experience this. Sometimes, crossing a river or a creek or walking under a waterfall is more than enough for this to happen. That is why many knowledgeable and experienced camper or backpacker knows how important it is to have a reliable waterproof backpacking or hiking backpack. A waterproof backpacking backpack or camping backpack comes with many benefits that you wouldn’t get from a typical everyday backpack. However, some of the latest waterproof backpacks imbued with the best waterproofing technology can be quite expensive which is why some people are on the fence when it comes to purchasing one. If you are looking for a reason or two as to why you should invest in one, we have outlined the best ones below for you. But before we dive into our top reasons why you need a waterproof backpack, let’s go over a brief description of what it actually is and how it is different from another popular type of outdoor backpack, the water-resistant backpack. The Best Waterproof Duffel Bags: Duffel Dry Bags for Travel & Outdoors If you've ever been concerned about your belongings getting wet while traveling or spending time outdoors---a waterproof duffel bag is your secret weapon. These durable and fully waterproof bags are ideal for situations when you just need the ultimate protection. A versatile travel backpack is great for everyday travel, but when you need to keep your gear safe from even the most extreme conditions, dry bag type duffels are a much better option. When traveling, especially in foreign climates, you just don't know what conditions you'll find yourself in---and who knows what happens to your bag in transit. I've learned to be better prepared and safe, than sorry. I've taken 10+ hour overnight bus journeys only to arrive at my destination finding that my luggage was moved from the secure and dry under bus storage to the top roof rack! Thankfully on this trip I decided chose decided to take my The North Face Base Camp Duffel, which keep all my belongings dry---even through a wet and rainy night. Your average travel backpack and luggage are great for the casual traveler, but if you are one who seeks adventure and outdoors, they often just don't cut it. Most travel bags will do a decent job keeping your gear dry when exposed to light rain, but a fully waterproof bag will ensure your stuff stays dry---no matter what. Cooler Bag Technology The original ice chest was made out of galvanized metal. Later versions were made from hard plastic. They were double-walled with a layer of dense Styrofoam in between which helped to keep the contents cool. Today's ice chests are still made this same basic way. Styrofoam was a suitable insulator, but it had to be relatively thick to maintain internal temperatures for an extended period of time. And, of course, Styrofoam is easily dented and broken, so it had to be encapsulated in a hard shell to prevent breakage. As such, ice chests have to be rigid. By contrast, cooler bags are not rigid. Instead, they are usually made from heavy but flexible fabrics, like polyester, on the outside. The inside is lined with heavy duty foil. In between the outer and inner layers are layers of materials like flexible foam, which are thin but dense and have the ability to maintain internal temperatures for several hours. This technology allows for a bag that is flexible and thin and, therefore, easy and convenient to transport. Also, unlike their rigid predecessors, cooler bag can be manufactured in a wider variety of sizes and shapes. How to get abandoned, lost and discarded ‘ghost’ fishing gear out of the ocean Fishing gear and plastic marine debris is a growing global issue. Abandoned, lost or discarded fishing gear — often called ghost gear — can contribute up to 76 per cent of all marine debris found during beach cleanups. Estimates of the weight of abandoned fish gear vary widely by region and by type of gear used. One study retrieved 14 tonnes from the northwestern Hawaiian Islands. In one fishing region in Nova Scotia, an estimated 22 tonnes of fishing gear remains at sea. Overall, an estimated 640,000 tonnes of ghost gear is lost globally in the oceans every year. This derelict fishing gear continues to catch fish, including commercially valuable and threatened species, and other marine fauna. For example, ghost gear, especially nets, are responsible for entangling seals and sea turtles. One abandoned fishing net in Puget Sound in the United States is expected to catch two invertebrates per day, one fish every three days and one seabird every five days. It also costs fishers. Ghost gear reduces catch rates and cuts into profits, it is expensive to replace and it can be dangerous — getting tangled in propellers and snarling anchors. What Makes a Good Fishing Cooler? Fishing cooler bag generally spend a lot of time in the sun and around the water, so it’s important that these coolers are both rust resistant and UV protected. Other benefits of a true fishing cooler will be the added insulation as well as odor and stain resistant materials. A good fishing cooler will also need to come equipped with a good seal to protect ice retention. There are many great fishing coolers to choose from, but have you ever thought about an insulated fish bag? These insulated bags can be a great alternative depending on how you plan to use your fishing cooler. What is a Fishing Bucket? Fishing bucket is frequently used by professional fisherman for the simple fact that they have been proven that the original weight of a fish can be maintained by placing it in an insulated bag with ice. Good insulated fish bags are lightweight, weighing much less than even small coolers. UV resistant, they are designed to hold ice all day; keeping your newly caught fish fresh for hours. These insulated fish bags should be leak proof and should be constructed in a way which makes them easy to clean. So, which is the best choice for your next fishing trip? Let’s take a look at the pros and cons of both.

Description: How to design PET preform mould PET preform mould for plastics materials (PET) have been made in some manner for centuries. Some of these PET preform moulds were fine works of art, as, for example, the moulds used by craftsmen in glass. The coming of the modern plastics moulding materials brought about great advancement in this old art, and transformed it into a science. Mass production PET preform moulding machinery has been developed, and new PET preform mould steels and alloys have been introduced to withstand severe service. Accuracy is a requirement in modern manufacturing, and PET preform moulded plastics are produced by steadily mounting standards of precision, which have necessitated new machine tool applications and methods. A PET preform mould may be defined as a form for shaping a plastic material ”PET” into a finished product-here is PET preform. PET preform moulds are made of plain carbon steel or of alloy steels, and are hardened to provide compressive strength and hard surfaces to take and maintain a high polish under severe wearing conditions. PET preform moulding materials require heat and usually pressure to achieve the plasticity necessary for them to flow into the shape of the mould cavity. Pressure is required to force the material into the cavity and to hold it to shape until it is set, and to give the casting or finished product the required strength. A PET preform mould must be polished to give the casting a good finish，and to allow it to be ejected easily. A mould for the general run of PET parts is divided into two halves which meet at the parting line. These halves are mounted on backing plates which are drilled to allow passage of steam or cooling water, and which carry the guide pins which aligning the halves of the PET preform mould. The mould halves and backing plates assembled constitute the PET preform mould proper. The fundamentals of mould design are discussed and applied to representative type PET preform moulds. The important compression PET preform mould types are classified for study; transfer and jet moulding are described; injection PET preform moulds are presented both as units and broken down into elements of design and construction. Methods of moulding screw threads are discussed; methods of PET preform mould sinking and applications of mould base standards are shown. mould building methods and equipment, moulded parts finishing, product design considerations and estimating methods are included as background information. A summary of practical points in PET preform mould design and construction, shrinkage charts and a nomenclature section provide a basic fund of data required by the serious learner. Since many factors enter into the design of plastics PET preform moulds, and into the design of products to be pet bottle mould, it is well for product designers, tool designers, and tool makers to have a common understanding of plastics PET preform moulds and PET preform moulding in order to cooperate to the fullest extent in making possible PET preform moulded products of high standards of quality and economy. Requirements for PET preform mould Designing To design plastics preform bottle mould, a plastics engineer should have an intimate knowledge of a proper design procedure which is based upon a knowledge of the characteristics of materials; of the technique of PET preform mould building; of the economics of each production schedule; of the tooling cost both to purchaser and to the PET preform mould manufacturers; of PET preform moulding equipment operation; of the special mould steels and alloys; and of the moulding and finishing facilities of his own plant. The design of plastics PET preform moulds includes, besides the design of the mould proper, the provision for mounting the mould in a press; the provision of means to eject the finished PET bottle mould casting; and a provision for temperature control. There are also finishing tools to be designed, such as drilling jigs, buffing attachments, holding fixtures, cooling fixtures, gages, and other devices for obtaining accurate and economical production. Two General Types of Plastic moulding in General Use There are two general types of moulding in general use compression and injection. A compression Mould is one which is open when the material is introduced, and which forms the material by heat and by the pressure of closing. An injection Mould is one which is closed before the material is introduced from an external heating, or plasticizing cylinder. Compression Moulds are usually operated in hydraulic presses; while injection Moulding presses have been developed for either mechanical or hydraulic operation. The Mould designer does not always have complete information on the product his Mould must produce. Usually a sketch or drawing is supplied, and sometimes a model. The model is useful since a Moulding or finishing feature may appear in three dimensions which would escape notice on a drawing. A model, while desirable, is not absolutely necessary, and most Moulds are built without their use. As the die or the die casting designer, the Mould designer can very frequently find details which may be altered slightly to allow more convenient and economical Moulding. The Mould designer can render a real service by making such suggestions for approval before completing his design. Single Stage Blow Molding Machine While PET bottle development was proceeding in the US, a large manufacturer of injection molding machines in Japan, was leading a project to develop a machine to make biaxially oriented PP (polypropylene) containers. They recognized that the prototype machine could be used to produce the new PET bottles and, in December 1975, the One-stage ASB-150 injection stretch blow moulding machine for making the new biaxial oriented PET bottles was unveiled. All one-stage injection stretch blow moulding machines derived from this original Stretch Blow design are referred to as classic one-stage machines, as the concept has long since been extended into other PET developments. The classic one-stage machines design is extremely versatile in that the same basic machine design can be used to make a wide variety of bottles and jars in all shapes and sizes. Two Stage Blow Molding Machine In the early developments, performs were made by continuously extruding a PET tube. To make these prefroms, a perform manufacturing machine that took a continuously extruded PET tube, heated and closed one end, and then heated the other and formed a thread finish by blow moulding. This process had a faster output rate, at 12000 preforms per hour, than the early injection moulding routes of 8 and 16 cavity moulds. Being extruded, the performs could be multilayered with barrier materials. The system was overtaken by injection moulded performs as the cavitation increased to 32 and beyond. The quality of the injection moulded (IM) neck, adding for example vent slots, made the IM finish preferable. Moreover, IM technology is available from more than one company, giving customers greater technical and commercial choice. Two-stage technology machines with six blow moulds operating at around 4000 bottles per hour. Subsequent mould and cooling development increased the output to 6000 bottles per hour. Two stage PET processing includes: Making performs by Injection Molding Blowing bottles by Stretch Blow Molding Because it is more flexible than one step processing, it is widely accepted in Plastic packaging market. You may choose to make preforms only or blow bottles only if you want to do one of them specially. Integrated Two Stage Blow Molding Machine In Integrated Two Stage approach the performs were made by more conventional injection moulding routes (with the number of cavities optimized to match the required output) and then, while still hot, were carried to a separate blowing machine with the optimized number of blow moulds to suit the required output. This was the first ‘integrated ‘approach to PET bottle making. Equipment developers took the ‘single-stage’ approach. Here the equipment had the same number of injection cavities as PET blowing mould. This was a more compact approach and proved ideal for small batch output with excellent glossy surfaces. Blow molding is a type of plastic forming process for creating hollow plastic products made from thermoplastic materials. The process involves heating and inflating a plastic tube known as a parison or preform. The parison is placed between two dies that contain the desired shape of the product. Air is then supplied to expand the tube causing the walls to become thinner and conform to the shape of the mold. Once the blowing process is complete, the product is then cooled, ejected, trimmed, and prepared for the secondary processes.Bottling and packaging are the main applications of blow molding which comprise about 49% of the global blow molding market share. This is followed by building and construction, consumer products, and transportation industries. The global market share of blow molding was estimated at around $78 billion in 2019 and is expected to grow annually by 2.8% from 2020 to 2027. Typical raw materials used are polyethylene (PE), polyethylene terephthalate (PET), and polypropylene (PP).Plastic blow molding originated from the ancient process of glass blowing. Both glass and plastic in their molten state can be formed easily by introducing small amounts of air inside the molten material. The first injection molding process for glass, known as free-blowing, was created around the 1st century BC. Glass mold-blowing was later developed as an alternative process that came about around the 1st century AD.The first blow molding material used other than glass was natural rubber. The process was patented by Samuel Armstrong in the 1850s. The next major advancement came around the 1930s with the development of the first blow molding machine by Plax Corporation. The process uses cellulose acetate as the raw material. Come 1939, low-density polyethylene (LDPE) was introduced by Imperial Chemical Industries from England. LDPE is more suitable for blow molding which then paved the way for further process development. By the 1950s, the commercialization of blow molding was completed, and the industry grew exponentially. This chapter discusses the general blow molding process. Blow molding is a fairly straightforward process that includes melting, homogenizing, extruding, molding (blowing), cooling, and ejection. Different manufacturing plants can employ additional processes such as additional cooling or heating cycles and additives and colorants compounding. These additional processes depend on the design and intended application of the final product. Plastic Resin Feeding or Charging: The first step in the blow molding process is plastic feeding. This is done by conveying the plastic pellets into the extruder hopper. Vacuum pumps draw pellets from big bags or bulk containers and transfer them into the raw material silos or hoppers. A rotary feeder at the bottom of the silo controls the rate of feeding into the plastifier or extruder. Compressed air is then used to convey the stored pellets to the extruder hopper. In other systems, plastic pellets from big bags or bins can be vacuum conveyed directly to the extruder hopper without the need for a separate conveying air system. Plasticizing or Melting: As the plastic resin enters and goes through the extrusion machine, it is melted by continuous kneading and heating. Electric heating elements or heating bands are wrapped around the extruder barrel to provide heat for melting the polymer. The extruder screw has different sections that serve a specific purpose. These are feeding, compressing, and metering. The extruder screw is designed to provide sufficient shearing and compression to homogenize and extrude the plastic. Parison Extrusion or Preform Injection: This process is the preparation of the parison or preform to be inflated. This is done by extruding the plastic through free extrusion or injection into a preform mold. The different processes in producing the preform are discussed in detail. Sealing or Clamping: Sealing or clamping involves a split die that captures the preform. The ends of the parison (extrusion blow molding) are sealed except for one hole, typically the container opening, where the compressed air will be injected. Inflation or Blow Molding: This step is where the plastic takes its form. Compressed air is introduced inside the preform. This inflates the preform until it is molded according to the profile of the die. Cooling and Ejecting: The next step is the cooling process. Typically, as the plastic touches the die, it cools at a predefined rate which stabilizes the dimensions of the product. After cooling, the mold opens and ejects the product. Trimming: Flashing is generally evident in extrusion blow molding. Most blow molding machines have auto deflashing features as the dies clamp the preform. But in some instances, flash is present at the top and bottom parts of the product, especially at the opening where compressed air is injected. This excess material is trimmed by a rotating knife. To minimize wastage, some systems collect the excess materials, grind them, and feed them back to the extrusion machine. Leak Test: This is the typical quality control method used in manufacturing bottles or packaging materials. In this step, either vacuum or compression is generated inside the container. The machine will then check if air enters or escapes the container by monitoring the pressure. If a leak is sensed from the container, it is rejected and fed back into the system.

Description: Stainless Steel Pipe Types Stainless steel is a versatile material comprised of a steel alloy and a small percentage of chromium — the addition of chromium adds to the material’s corrosion resistance, a trait that earned stainless steel its name. Because stainless steel is also low-maintenance, oxidation resistant, and doesn’t affect other metals it comes in contact with, it is frequently used in a large array of applications, especially in piping and tubing manufacturing. Based on the end use of the pipe, stainless pipe is broken down into several categories. Since the development of stainless steel over hundred years ago, it has become world’s most used and popular material. Since stainless steel has the notable corrosion resistance that helps in increasing features with chromium content. The resistance can be shown in reducing acids as well as against pitting attacks such as in chloride solutions. It requires low maintenance, and is familiar to luster thus making it an ideal and best material for SS pipes. This versatile material is indispensible in wide industries. This may contain number of application especially for SS pipes that benefit user with positive properties. Iron-containing alloys made from more than two chemical elements are known as stainless steel. It is widely been used in comprehensive range of applications. Stainless steel alloy is basically steel alloy with iron, nickel, and chromium percentage contents in abundance. The stainless steel has been in presence for centuries, since it is vulnerable toward corrosion and works better in tough condition. The stainless steel gets recognized late in year 1800’s with a combination of iron-chromium with offered rust resistance. Since, then it is mold into stainless steel pipes so that it gets used for number of industrial applications. In 1912, a researcher of brown-firth laboratory founded a martensitic SS alloy finally. The new material got labeled as Staybrite. The stainless steel alloy comprises of iron alloy with minimum amount of chromium up to 10.5%. You can see tremendous variety of alloys in the market, the only thing they differ is in chemical composition. The alloying elements are titanium, nickel, carbon, copper, nitrogen that can boost formability, strength, and other SS properties. The stainless steel pipe is available in different product type such as welded pipes and seamless pipes. The composition may vary and this makes it possible to use it in respective industries. Generic industrial company use stainless steel pipe for regular use. Different Types of Steel Tubing and Stainless Steel Piping Pipes and tubes are sometimes difficult to classify, and tend to be distinguished based on function. In addition to these classifications, stainless steel is also distinguished by type and grade. 304 Stainless Steel Pipe For tubing and piping applications, type 304 stainless steel is a common selection because it is highly chemical- and corrosion-resistant. However, type 304 stainless steel is not compatible with applications where temperatures fall between 800 and 1640 degrees Fahrenheit (F) because it is prone to carbide precipitation, a result of the material’s .08 percent carbon content limit. Stainless steel type 304L circumvents this problem because it has a lower carbon content limit, and therefore can be subjected to welding and higher temperature applications. Other types of stainless steel often possess additives (such as nickel or molybdenum) which strengthen traits that are desirable in particular applications. Stainless Steel Tubing for General Corrosion-Resistance Stainless tube general category of steel is appropriate for applications that require corrosion resistance above other traits. Ferritic or martensitic types of steel (those made with the most chromium) are manufactured to be either heat-treated or annealed. Austenitic Stainless steels (those with high chromium and nickel contents) offer even more resistance, and can be used under the same general conditions as ferritic and martensitic types. Stainless Steel Pressure Pipe This type of stainless steel pipe is made from either solid chromium or a chromium and nickel combination. Types of stainless steel pressure pipe include seamless and welded pipe, electric fusion welded pipe for high-pressure applications, large diameter welded pipe for corrosive or high-temperature applications, and seamless and welded ferritic and austenitic stainless steel pipe. Stainless Steel Sanitary Tubing For applications where stainless steel tubing or piping must come into contact with food and other sensitive products, sanitation is a high priority. Stainless steel sanitary tubing is used in such applications because it has high corrosion-resistance, doesn’t tarnish, and is easy to keep clean. For specific applications, different tolerances can be achieved. The grade typically used for these applications is ASTMA270. Stainless Steel Mechanical Tubing In applications such as cylinders, bearings, and other hollow formed parts, stainless steel mechanical tubing is typically used. Tubing can manipulated to have a variety of cross-sectional shapes, such as square and rectangular, in addition to the more traditional, round tubing cross-section. Typically, ASTMA 511 and A554 grades are employed for mechanical tubing applications. Stainless Steel Aircraft Tubing In highly-specific aircraft applications, chromium and nickel type stainless steel is used because of their heat and corrosion-resistance. Found in applications that require high-strength, stainless steel aircraft tubing can be work-hardened or welded, although work-hardened pieces shouldn’t be used with some kinds of corrosive substances. Low-carbon types of stainless steel are a common choice for welded parts. For applications that require seamless and welded tubing in larger sizes (1.6 to 125 mm in outside diameter), aircraft structural tubing is used—this type of stainless steel is manufactured according to Aerospace Material Specifications (AMS) or Military Specifications (MIL Specs). Aircraft Hydraulic-Line Tubing Another type of aircraft tubing, aircraft hydraulic-line tubing is used in aerospace applications as fuel-injection lines and hydraulic systems, and tends to be small. It is often manufactured from types 304 or 304 L stainless steel because of the steel’s high-strength, corrosion-resistance, and ductility. AP pipe, or Acid Pickling, uses acidic solutions such as nitric acid and fluorine acid to Remove the oxide layer of the steel pipe. Cheap and fast, but easy to cause grain boundary corrosion and rough inner and outer surfaces The roughness is easy to have suspended impurities attached. AP literally means pickling surface, and in the category of clean products, it means pickling surface + oil-free cleaning MP Tube-Mechanically Polished Pipe MP tube : Mechanical polishing is often used for the oxide layer on the surface of steel pipes, The brightness and effect of holes and scratches depend on the type of processing method. In addition, after mechanical polishing Although it is more beautiful, it will reduce the corrosion resistance, so when used in a corrosive environment, it needs to be passivated. reason. And there are often polishing material residues on the surface of the steel pipe BA tube-Bright Annealed Pipe Bright Annealed Pipe BA is the bright annealing Bright Annealing steel pipe in the process of drawing will definitely need grease lubrication and the grain will also be deformed due to processing. In order to avoid this grease remaining in the steel pipe, in addition to cleaning the steel pipe, you can also use high temperature annealing at high temperature to eliminate deformation, using argon as the furnace atmosphere, and further clean the steel pipe by combining argon with the carbon and oxygen on the surface of the steel pipe. The surface has a bright surface effect, so this method of using pure argon annealing to heat and quickly cool to brighten the bright surface is called bright annealing. Although the use of this method to brighten the surface can ensure that the steel pipe is fully clean and free of any external pollution. However, if the brightness of this surface is compared with other polishing methods mechanical, chemical, and electrolytic, it will feel like a matte surface. Of course, the effect is also related to the argon content and the number of heating times. EP tube ElectroPolished Pipe (EP 0 (Electro Polishing) Electropolishing is the use of anodizing method to appropriately adjust the voltage, current, acid composition, and polishing time through the principle of electrochemistry. Not only can the surface become bright, Smooth and clean effect 0 can also improve the surface corrosion resistance, so it is the best surface brightening method, of course, its cost and technology also increase. However, because electrolytic polishing will highlight the original state of the steel pipe surface, if the steel pipe surface has serious scratches and holes.

Description: WHAT IS CORRUGATED CARDBOARD AND WHY IS IT ESSENTIAL FOR SHIPPING GOODS? Did you know that approximately 95% of all products in North America are shipped in corrugated cardboard containers? In fact, corrugated boxes are such an essential part of our supply chain, that packaging manufacturers were able to continue operations through the COVID shutdowns as essential business entities. Corrugated cardboard is very durable by design and consists of multiple layers: an outside liner, an inside liner, and a fluted layer between the two. The three layers are glued together to create corrugated cardboard. Also referred to as corrugated fiberboard, the material offers significant advantages over other options when it comes to shipping. The Advantages of Corrugated Cartons for Shipping Plain and simple, corrugated cardboard boxes provide the right level of protection for goods in transit. Shipping cartons can go through a lot from the warehouse to their final destination. Corrugated packages are designed to survive bad weather, bumpy roads, sudden temperature changes, or rough handling–all while keeping products safely intact. While no corrugated package is completely indestructible, the materials and makeup of these containers are more likely to protect your products in transit. Your customers are more likely to be happy when products arrive in top condition. If customers receive a damaged or broken item, they will be unhappy. And we all know that unhappy customers are less likely to make a repeat purchase. Even though corrugated cardboard packaging is very sturdy, it is also lightweight. This can help keep shipping costs down. Corrugated boxes can be fashioned into a variety of shapes, allowing your company more control over the kind of unboxing experience your consumers will have when your products arrive. This is especially important for e-commerce businesses that ship consumer goods. And finally, corrugated cardboard boxes are constructed of renewably-sourced materials. Since they are made mostly from trees, a renewable resource, this kind of packaging is very easy to recycle. When recycled properly, corrugated cardboard packaging is processed into paper products and even new boxes. What’s also great about corrugated cardboard is its multi-use properties. Thanks to the material’s durability, many corrugated packages can be reused multiple times before they even hit the recycle bin. The sustainability of corrugated cardboard is also what makes this material very affordable. How Cosmetics Boxes Help Your Brand Every woman wants to look attractive and beautiful. For this purpose, a variety of cosmetic products are used. Cosmetics, itself is a symbol of beauty. Therefore its packaging should be such that which complements the product. Every day, a number of cosmetic brands are introduced in the market offering a wide range of cosmetic products at more competitive prices. It becomes extremely difficult for the customers to choose among a number of alternates. Packaging plays an important role in this regard. The brands which succeed in creating perfectly designed cosmetics boxes for their product range wins the race. As the packaging box is the first thing with which customers get interacted. So the custom printed boxes should be attractive enough to grasp the attention of the customers at first sight. Moreover, your display packaging plays an imperative role in promoting your brand and making it recognizable for the customers. Below are some of the ways how cosmetics boxes help your brand: Protect The Products Using cosmetics boxes for your product range is the best way to protect your products from any damage. When a product is shipped, the chance of damage increases due to various reasons like mishandling, carelessness, stacking or the vehicle may get accident etc. Using perfume boxes for your products reduces the risk of potential hazards. They keep the delicate items safe during transportation, storage, shipment or when placed on retail shelves. Cosmetic are the things which every woman prefer to try before purchase. Cosmetics boxes at TheCustomboxes provide the products from accidental damage, fall or mishandling by the users. They are designed from highly durable cardboard material. It acts as moisture resistant and saves the content from humidity, sunlight or changes in temperature. This increases the useful life of the product. Only if a company ensures safe delivery of its products to the customers, he is able to compete in the market. Speed Up Decision Making Process Designing the cosmetic display packaging in an attractive manner is a great way to speed up the decision making process. Heavily promoting the product on media is not only the way to boost up the sales. Rather packaging is a thing which creates a great difference. Well designed custom printed boxes create a positive impact on the minds of the customers thus stimulating their purchase behavior. As it’s a matter of just a few seconds, so customers do not have time to evaluate the pros and cons of a product when they shop. Therefore, cosmetic packaging should be such that it puts a valuable first impression on the customers and speeds up the decision making process. Attracts The Customers Shoppers are influenced by the cosmetics boxes which look attractive and different from others. Customers always prefer something innovative. A packaging which creates a great shelf impact has the ability to attract a heap of customers. Color plays an important role in this aspect. Different colors create a different psychological impact on the minds of the customers. Therefore, before finalizing a color for your brand, make an analysis that who are your target customers and which influence them the most. Customers never give a second chance to the cosmetic packaging which looks unattractive. So it’s one time chance to win the race. Many of the brands have changed their cosmetic packaging to attractive gift boxes to fascinate the customers. It’s a useful tactic which proves highly significant. What is the Future of Food Box On Monday, March 22, the USDA held a 12-hour listening session to hear feedback from the public about the Farmers to Families Food Box Program. The program was created almost a year ago at the peak of the pandemic lockdown. It was designed to quickly move surplus commodities from farmers to consumers in need and hopefully support some idled workers and distribution systems in the process. The goals were broad, and the rules were loose. There were many criticisms that the rules were too loose and the cost was too high, and about four months in, the USDA put more structure into place around the program. At that point, the program seemed to shift the balance more toward providing food for people in need rather than supporting farmers or the supply chain. The USDA was providing direct payments to farmers and the media had stopped reporting on crops being plowed under and milk being dumped. Yet, there was plenty of footage of cars lined up for miles to receive the food box. That shift to helping consumers, and the earlier criticisms, led the USDA to focus more on cost per box in the later rounds of the program. The Truth About Paper Bags These days, when you hear the question, “Paper or plastic?” the answer is an almost instinctive “Paper!” We all know that plastic is terrible for the environment, and that plastic bags, in particular, are clogging up our oceans, choking our wildlife and generally wreaking havoc on the world. Because of this, and because the paper bag industry has positioned itself as the solution for decades now, we rarely stop to ask a critical question: Is paper actually that much better? The truth is, no, it’s not. Paper does a lot of damage to the Earth as well, and every time we unthinkingly grab a few bags at the checkout stand, we contribute to that damage. It’s time to learn the truth about paper bag, so we can start making better choices today. Because the answer to “Paper or plastic?” should actually be “Neither … I brought my own.” Not That Much Better Than Plastic Paper bags just seem friendlier to the environment, right? They don’t have that slick petroleum look like plastic bags do; they’re a cheerful kraft color; they fold up neatly to stack in your cupboard for next time (assuming they didn’t get destroyed this time). But research, such as this report, makes clear that plastic really doesn’t have much on plastic. To wit: It doesn’t break down any faster than plastic in landfills. That’s because, while paper breaks down much faster under ideal conditions, landfills are not ideal conditions. The lack of light, air and oxygen means pretty much nothing decomposes, so paper and plastic are destined to spend equal amounts of time there. Gift paper bags are bigger than plastic, which means they take up more space in landfills. They’re recycled at a higher rate, which mitigates that fact, but that still means they still have a greater per-bag impact on landfills. It takes four times as much energy to manufacture a paper bag, as compared to plastic, and the raw materials have to come from trees, a natural resource that is otherwise carbon-fixing. Making paper bags not only adds waste to the world, it kills one of our greatest tools for fighting pollution. Paper bags generate 70 more air pollutants than plastic. They generate 50 times more water pollutants than plastic. It takes 91 percent less energy to recycle a plastic bag than it does a paper bag. Shopping paper bags are very thick, so shipping them costs more fuel per bag. This report is admittedly biased toward plastic (and reusable bags), but if this is starting to sound like a vote for plastic bags, think again. Plastic leaches chemicals into our oceans and waterways, breaks into small pieces and accumulates in the stomachs of baby birds, strangles fish and collects into great seafaring clumps that become islands and continent-sized garbage patches. The point isn’t that plastic is good; it’s that our unwavering assumption that paper’s okay is wrong. Here are a few more reasons not to trust that paper bag’s cheerful, eco-friendly-looking fa?ade.

Description: HOW TO CHOOSE THE RIGHT LED SHOEBOX LIGHTS FOR YOUR PARKING LOT If you are considering upgrading your lights to LED, the parking lot lights should always be the first one to take into consideration, because of the large service area of parking lot and the high energy consumption of traditional metal halide parking lot light. It’s not easy to research dozens of websites to put all the pieces of the puzzle together and answer all of your questions about what is the right LED shoe box light Fixture for your needs. For this reason, we prepared some tips about shoebox light, Parking Lot and Area Lighting in this article. Here are several things you need to know before converting your facility: 1. Type of facility: Is the site retail, warehouse or other commercial use? 2. Type of fixture or lamp: Wall Packs, Shoeboxes, Flood Lamp 3. Wattage of existing lamps: This gives your LED manufacture insight to the LED equivalent needed. 4. Line voltage: LED products are voltage specific, and the LED installer will need to know this detail. 5. Needs from the changes: To increase/decrease the lighting output, address a specific problem or area, meet a specific specification or code 6. The best color of light: The sun is 5778k, and in the LED industry, 5000k is considered to be the closest to natural sunlight. Outdoor lighting is often oriented to a 5000k color. 7. Quality of LED products: Quality means you trust you will not have any warranty issues, service means if you do have any issues, the integrity of service will be tasked to work its magic. What is high bay lighting, and what applications benefit from it? Whenever a large indoor space needs to be illuminated, high bay lighting is usually appropriate. Consider spaces like manufacturing facilities, gymnasiums, warehouses, large department stores, factories, and more; these facilities are typically vast and cover a lot of vertical as well as horizontal space. This requires powerful lighting to provide the appropriate foot-candle levels to adequately illuminate. High bay lighting fixtures typically hang from the ceiling via hooks, chains, or pendants, or they may be fixed to the ceiling directly (similar to troffer lights). The image above features high bay lighting in action. Various industries and facilities require high bay lighting. Some of the most common are: Warehouses Industrial facilities (read more about Industrial LED lighting here) Manufacturing facilities School and university gymnasiums Municipal facilities like community centers or recreation centers Commercial applications like department stores Why choose LED high bay lights instead of metal halide, fluorescent, or other conventional high bay lights? Historically, various lighting technologies were (and still are) used in warehouse and industrial settings when high bay lights were required. Some of the most common include metal halide (MH), high pressure sodium (HPS), and fluorescent. While each of these bulbs have their merits, industrial LED lighting outperforms its conventional counterparts in important ways. Let’s take a look at some of the various considerations when deciding whether an LED retrofit is appropriate for your warehouse or industrial space. Industrial LED lighting vs metal halide high bay light: If you’ve ever been to a ballgame, you've likely seen metal halide illuminating the field. MH lamps are common in sporting and warehouse/industrial uses (as well as any setting where large, high spaces need to be illuminated). Benefits of MH lights include decent color rendering and comparatively adequate foot-candle levels (as opposed to other types of conventional bulbs). Some of their major drawbacks are a long time to warm up (sometimes 15-30 minutes) and a high cost to maintain, and their failure characteristics include flickering on and off. This is in addition to the fact that much of the energy they produce is wasted as heat. Read more about LED versus Metal Halide Lights. Linear LED high bay light vs high pressure sodium (HPS) lights: HPS lights are often used in warehouse, industrial, business, and recreational facilities where high bay lighting is appropriate. Their benefits include cheap selling price, high energy efficiency (low operating costs), and a relatively long lifespan. HPS lighting technology retains these advantages over most conventional bulbs, but they lose on all three counts to LED high bay lighting. The downsides of HPS bulbs include the worst color rendering on the market and a warm up period. Read more about LED versus High Pressure and Low Pressure Sodium Lights. Industrial LED lighting vs fluorescent lighting: Though somewhat less common, fluorescent lighting is sometimes utilized in warehouse or industrial applications (primarily T12, T8, and T5 lights). The benefits of fluorescent lights include cheaper initial costs and relatively high efficiency (especially when compared to other conventional bulbs). Downsides include the presence of toxic mercury (which requires certain waste disposal procedures), decreased lifetime if switched on and off, and requiring a ballast to stabilize the light. Read more about LED versus Fluorescent Lighting. It’s no secret that LED lighting technology has surpassed the capabilities of conventional lighting in important ways. In addition to the considerations discussed above, there are three general benefits of LED lighting that apply to all lighting applications. Decreased maintenance requirements. As discussed above, LED lights have a lifespan that is four to forty times longer than many conventional bulbs. This means fewer replacements for bulbs that wear out. LED lighting technology also generates light differently than typical fuel and filament lighting by using a diode (learn more in this blog). This means that there are fewer moving pieces to break, and consequently, fewer repairs or replacements. Maintenance is an especially important consideration when it comes to industrial lighting or warehouse lighting. By definition, high bay lights have higher mounting heights, which means that changing a bulb requires some specialized equipment or creativity. Scaffolding, catwalks, and hydraulic lifts are generally used to swap or replace bulbs, and each of these can result in additional maintenance or equipment costs. Again, the lifespan of industrial LED lighting means that fixtures need to be changed much less often, which means savings for your bottom line. Improved lighting quality. Industrial LED lighting and high bay lights will typically score better in a head-to-head comparisons against most other bulbs when it comes to color rendering index (CRI), correlated color temperature (CCT), and foot candles. CRI is a measurement of a light’s ability to reveal the actual color of objects as compared to an ideal light source (natural light). In non-technical terms, CCT generally describes the “glow” given off by a bulb - is it warm (reddish), or cold (bluish white)? Foot candles compare the amount of light coming from a source and the amount of light hitting the desired surface; they’re basically a measure of efficiency. On all three fronts, LED lights perform very well. (Read more about CRI, CCT, and foot candles here.) Increased energy efficiency. Not only do LED lights generate light differently, they also distribute light differently than conventional lighting solutions, which results in less energy required to provide the same output. How does that work? First, many conventional lights waste a lot of the energy they produce by emitting it as heat (this is especially the case with metal halide lighting). Second, most conventional lights are omnidirectional, which means that they output light in 360 degrees. So, a lot of light is wasted pointing at a ceiling, or being diluted because it has to be redirected through the use of fixtures. Industrial LED lighting for applications that require high bay lights eliminates these two problems of wasted energy (through heat loss and omnidirectional emission). Indoor Plant Lighting Indoor plant lighting gives plants most of the energy they need to grow, thrive, even to stay alive. The proper type of indoor plant light is more than just a matter of giving a plant the brightness it needs. There are three lighting factors that control growth of a plant: Amount of light: number of hours of daylight on your plants Intensity of light: levels of light from full sun to full shade Spectrum: warm and cool colors Gas Station Lights Every location has its own unique lighting needs. When it comes to gas station lights, there are a few fixtures that are exceptionally well suited to this location. Let's take a look at a few of the most common solutions for gas station lighting. LED When looking at fixture options, you should first determine the right lamping solution to narrow down the choices. LED is the best choice for this unique location. LED offers a higher lumen output for a brighter fixture while operating on a lower wattage which saves on energy for utility costs. LED is also a no heat solution which means the life of the fixture will be protected from heat damage. Another benefit of LED is that the lamps last a long time to save on replacement costs and maintenance spent on maintaining fixtures. Best of all, LED is available in the most commonly used gas station lighting solutions. Canopy Lights When looking at gas station lighting, the most obvious area is the canopy. This is where the majority of the business happens since customers pump gas under the canopy. It is also important to make sure this area is well-lit, so customers can see it clearly from the road at night. A well-lit canopy also gives a feeling of safety and security when pumping gas at night that most customers expect. In fact, most customer will pass up a poorly lit gas canopy in favor of a brighter one, so this area directly impacts your business. This is where canopy lights come in and save the day! Canopy lights are made specifically for this type of environment, so they offer such features as vandal proof options, wet rated listings, durable polycarbonate lenses, and bright, powerful illumination where you need it most. Canopy lights come in choices of thin profile to save on space and low profile for lower canopies in terms of height. Parking Lot Lights While the canopy lights are the main draw on the exterior, you will still need additional parking lot lighting. Parking lot lighting is necessary for any surrounding parking spaces not covered by the canopy. They can also be used to add visibility to roads leading to the parking lot or behind the building for added safety and security. When choosing parking lot lights, you can go with either cobra head or floodlights. Floodlights are ideal if you have a larger lot whereas cobra head is ideal for smaller lots. Interior Lights While the outside lighting is important, the inside is just as crucial to a successful lighting plan. For interior gas station lighting, there are several great options to consider. A few of the most common are recessed troffer-style and surface mounted fixtures. Both options offer an easy to install and maintain solution to meet the needs of this location. In this type of location, you want to avoid suspended or chain fixtures since they can create more shadows and detract from the clean, bright atmosphere your customers appreciate.
