  HDPE vs. PVC There are continuous debates as to which pipe is the best to work with for what type project. The following is an effort to compare the advantages and disadvantages to using HDPE versus PVC pipe. Every effort will be made to be impartial on the pro ’ s and con ’ s. That said, we are a manufacturer of HDPE pipe.  HDPE pipe  has been the material of choice for trenchless installation practices almost since the technology first appeared in the mid-to late 1960s. Durability PVC is a fairly durable vinyl polymer while HDPE is a thermoplastic made from petroleum. They are both considered plastics. When comparing failure ratings, PVC has shown to be higher than HDPE. PVC has a rating of one in 48,650 events compared to HPDE with one in 10,000,000. These failure events included rain stress, wind, heat or cold. HDPE is known to be more durable in these events. PVC is shown to be more useful in one-time projects. HDPE Pipe Joining When joining PVC, gasket or gluing sealant must be

Color coated steel Coil  is a flat steel product on which protective decorative paint is applied. A polymer coating is available in various colours as well as a matte, lustre or decorative natural finish (granite, wood, etc). Organic coated galvanised steel is corrosion-resistant, has excellent mechanical properties and can be formed, profiled or stamped. Application of colour-coated steel coils The consumers of colour-coated steel products include the construction, home appliance, furniture, consumer goods and automotive industries. Colour-coated coils are most widely used in construction, which consumes more than half of the amount produced worldwide. The coating type directly depends on the exposure conditions. Colour-coated steel is used in various interior finishing work and facade elements. In the manufacture of appliances and commodities, both standard cold / hot- rolled steel and galvanised steel of various grades meant for bending and deep-drawing are used as feedstock for col

Do you all have at least one  scarf necklace  in your hands? Is it still the only way to wear it around the neck? Want to try more different ways of wearing, but don't know where to start? Don't worry, seeing this article, how can you still wear it around your neck in the same way. Of course, it's how you get your personality, and it's guaranteed to let you find the way you want. The correct way to open the scarf necklace, 3 ways to wear it every day Bag decoration tape The most classic type of scarf necklace is to wrap the whole scarf necklace on the hand strap of the bag. If it is a basic color bag, the wrapped scarf necklace can become a high-end bag immediately. How many different scarf necklaces can be matched with the same bag can present as many atmospheres. How much money did you save buying bags? But if your bag is a messenger bag style, the shoulder strap is relatively long, and the scarf necklace is not long enough, you can tie a bow on the shoulder strap, an

Custom metal stamping   is the most common requirement in most industries around the world. Metal presses are used to produce the right stamped parts according to the customer's requirements. In this case, custom metal stamping dies play an important role. There are many companies offering this service, but only a few can be called the best for sure. Here are some important things to remember if you want to get the best part.   Your Company's Reputation Consider your company's reputation first. Well, when you work with a custom metal stamping company, you need to consider this option carefully. You have built a reputation in the marketplace for quality products and reliable standards, and any compromise here could mean disaster. Therefore, it is important to know up front if the manufacturer will be able to provide you with your preferred stamping die parts on time. Another important thing to consider is their reputation in the marketplace for custom metal stamping. Stainle

      What are the benefits of a neck massager? 1. Relieve fatigue The neck massager can effectively eliminate the fatigue and discomfort of the body, and can play a good role in relieving neck pain. The neck massager is a great boon for people who are prone to stiff neck when sleeping. It can solve the restricted neck movement after stiff neck. For sedentary office workers, teachers who work at desks for a long time, drivers who drive for a long time and other professionals, the neck massager is a good invention. 2. Promote blood circulation The  neck massager   can promote the circulation of blood in the neck through vibration or beating massage, eliminate the pain caused by poor blood in the middle-aged, thereby improving the quality of sleep and allowing the brain to get sufficient oxygen. 3. Prevent cervical spondylosis Neck massager can relieve neck fatigue, promote neck blood circulation, and have a good preventive effect on cervical spondylosis, especially for sedentary office

Because of their combination of properties, castability and cost effectiveness, gray and ductile iron are the dominant metals (based on weight) produced in metalcasting facilities today. When sourcing, designing and purchasing ductile and gray iron castings, a number of variables must be considered when choosing between the two. This comparison of gray and ductile iron will help designers and purchasers decide which alloy is suitable for a specific cast component. Gray iron is the preferred material when seeking low-cost, complex geometries with strength and high density. Gray iron can be used for a wide range of applications, from table legs and bases to large fountains and building facades. Gray iron is particularly good for applications in which vibration damping is required, such as engine blocks and frames for manufacturing equipment. For higher strength applications, ductile iron can be used. Ductile iron, because of its strength and ductility, often is specified in severe applic

Everyone has used corrugated boxes. But have you ever wondered how they are made? Does it need to be folded by hand or can it be done simply using a  carton forming machine ? You should know that corrugated boxes are made from trees. Below we will discuss the box manufacturing process step by step. Steps in Box Manufacturing 1. The tree While we ideally look for recycled cardboard for box production, at some point, a cardboard box begins life in the form of a tree. Typically, the trees used for box manufacturing are cork trees such as pine and fir. They are chosen because they have long fibers that help create a smooth surface for the cardboard and create the tension that adds strength. Many manufacturers will choose wood from sustainable and managed woodlands; this means that any trees that are cut down will be replaced to help maintain the ecosystem of the forest. Depending on the tree used, the paper and board created will have different colors. For example, silver birch will produc

 Although printing on  cosmetics containers  and packages looks the same at first glance, there are actually various printing methods.   The following items are explained here. ● Silkscreen printing ● Pad printing ● Offset printing ● Hot-dry printing ● UV printing ● Inkjet printing ● Coating ● Vapor Deposition  ● Hot stamp printing ● Shrink  ● In-mold printing ● Adhesive labels *The methods employed differ depending on the container (material) manufacturer, finish, quality, etc.     1. Silkscreen printing (silk printing) A technique for printing by using a silkscreen made of nylon, Tetoron, or other synthetic fiber (silk used in the past) attached to a frame, filling the mesh of the silk with emulsion in areas not to be printed, and rubbing the paint with a squeegee while applying pressure. The printing process is repeated by printing one color and drying, and a printing plate for the number of colors is required. *Color compositing is not possible. The printed ink layer is thicker and

  Pruning and maintaining trees is an important part of their health and productivity. Having a tree pruner on hand is a smart way to keep your trees looking great. Because ladders can be dangerous, having a   telescopic tree pruner   allows you to trim branches of all heights from the safety of the ground.   Before you choose to  buy any telescopic tree pruner , you need to decide whether you want a manual or gas-powered pruner. Gas-powered telescopic tree pruner models are heavier and are suitable for bigger jobs, such as cutting larger branches. Manual telescopic tree pruners are used for smaller jobs and cutting thinner branches.   Manual pruning shears are more labor intensive than gas-powered pruning shears, but they are also cheaper, more environmentally friendly and lighter in weight. Most people will be happy with a manual model, but a commercial tree pruner or gardener may want to consider using a gas-powered model.   Telescopic Tree Pruner   If you are buying a manual telesc
