PE pipe production line is made of polyethylene as the main raw material, adding antioxidants, carbon black and coloring material. The utility model has the advantages of small density, high specific strength, low temperature resistance and good toughness, and the brittleness temperature can reach 80 DEG C.

PE plastic can be used molding methods, film, sheet, pipe, profile and other products; and for cutting, bonding and welding processing. Plastic is easy to dye, can be made into a variety of bright colors; also can be printing, electroplating, printing and embossing processing, making plastic has a wealth of decorative effect.

Most plastics to acid, alkali and salt corrosion resistance than metal materials and inorganic materials, particularly suitable for chemical factory doors and windows, floor, walls etc.; thermoplastic plastics can be dissolved by some organic solvents, thermosetting plastics cannot be dissolved, only a set of possible swelling. Plastic has a good resistance to environmental water, corrosion resistance, low water absorption, can be widely used in waterproof and moisture-proof works.

Generally not high heat resistance of PE plastic pipe production line, the load at high temperature are softening deformation, even decomposition, metamorphism, deformation temperature of 60 DEG C - 120 common thermoplastic heat, only a small number of varieties can be used for a long time at 200 degrees celsius. Some plastics are easy to fire or slow to burn, and they also produce a lot of poisonous smoke when burning. Plastech linear expansion coefficient, 3 to 10 times larger than the metal. As a result, the temperature is large enough to cause material damage due to the accumulation of thermal stresses.

Because of its excellent performance and low temperature toughness, resistance to the vehicle and mechanical vibration, freeze-thaw action and operation of a sudden change in pressure damage, therefore, can be used for coil insertion or plow construction, convenient construction and low cost; and because the wall smooth, medium flow resistance is small, medium low energy consumption that is not affected by chemical corrosion medium conveying liquid hydrocarbon. Medium and high density PE pipes are suitable for urban gas and natural gas pipelines. Low density PE pipe is suitable for drinking water, cable ducts, agricultural spraying pipeline, pipeline pumping station etc.. PE pipe can also be used in the mining industry, water supply and drainage pipe duct etc..
