3 PE anticorrosive pipe
The 3PE epoxy powder composite steel pipe (also known as TPEP anti-corrosion pipe) is an upgrade product on the basis of the epoxy composite steel pipe in the outer polyethylene, which is the most advanced anti-corrosion form of buried long distance pipeline at present. The self-developed fourth-generation large-diameter pipeline's new anti-corrosion outer wall adopts thermal fusion and winding process to form a three-layer structure anti-corrosion layer with the bottom epoxy resin, the middle adhesive and the outer polyethylene. The inner wall adopts thermal spraying epoxy powder for anti-corrosion, and the powder is evenly coated on the surface of the pipe body after being heated and melted at high temperature. At the same time, it has high strength of epoxy, low water absorption of PE and good softness of hot melt adhesive, with high anti-corrosion reliability.
1 at the end of glue. Before extruding the polyethylene coating, a sealing rubber layer should be applied to the pipe surface. The performance index of base gum is based on the hot melt adhesive of asphalt type used before. National standards on the base of the softening point, heating loss, needle penetration, thermal decomposition temperature, self-repair, shear strength, peel strength, and so on. However, it is proved that the adhesive still has many disadvantages, such as low temperature resistance and poor bonding performance. Some foreign people use butyl glue and the latest resin glue, and domestic base glue is one of the key research topics.
2 polyethylene. The density of polyethylene can range from 0, 91 to 0, 96g /c. The performance is different because of the different densities. Since there is no short bifurcation in high density polyethylene, its junction bii, degree, secondary strength, fracture rate, tear strength, drug resistance is much better than low density polyethylene, which can produce corrosion coatings with different properties and different prices according to the needs of users. High density polyethylene coated pipe (Huang Jiake) the applicable temperature below so ℃, bottom density polyethylene coated pipe (green jacket) the applicable temperature below 60 ℃.
3. Production method. Polyethylene anticorrosive coating used flow dipping process and powder dispersing and melting process, etc. Recently, the production method is basically extrusion method. Bibian of small diameter (15-800mm) is the adhesive circular mould method (with protective layer), and bibian of human diameter (400-1600mm) is the tight t-mould method (no protective layer, single layer). Recently, the use of close - fitting method on small and medium diameter pipe is increasing gradually. In the future, this method may be widely used on anti-corrosion steel pipe

The outer diameter is the measurement of the pipe's outside surface from one end to the other. It is typically expressed in millimeters or inches and plays a critical role in determining the pipe's strength and carrying capacity. Different applications require different OD sizes, which can range from a few millimeters to several feet. The wall thickness refers to the distance between the pipe's outer and inner surfaces. It is measured in millimeters or inches and is crucial for determining the pipe's durability and resistance to pressure. Thicker walls can handle higher pressure, making them suitable for applications that require transporting liquids or gases under high pressure. Steel pipes are generally specified in meters or feet for their length. Standard pipe lengths are often 6 or 12 meters (20 or 40 feet), but custom lengths can be requested based on project requirements. It is important to note that longer pipes may require additional support to prevent sagging or structural issues. In addition to these primary measurements, steel pipes may also be specified based on other factors such as material grade, manufacturing standard, and surface finish. Material grade refers to the quality and composition of the steel used in the pipe, determining its strength and corrosion resistance. Manufacturing standards, such as ASTM or API, ensure that the pipes meet specific quality and performance criteria. Surface finish specifications may include factors like galvanized coating, providing protection against corrosion or other specific requirements based on the intended application. Overall, the measurement and specification of steel pipes involve considering the outer diameter, wall thickness, length, material grade, manufacturing standard, and surface finish. These parameters are crucial in determining the suitability of the pipe for various applications and ensuring its performance and durability in different environments.
