Compared with traditional pipe, PE pipe has the characteristics of good flexibility, low density, high compressive strength and quality, good anti-corrosion insulation, low temperature to the environment, easy color, convenient construction and equipment. Therefore, PE pipe is widely used in the construction of municipal engineering, water supply and drainage engineering, agricultural machinery and agricultural water-saving irrigation, industrial production sewage treatment, heating and heating, cable threading, mineral transportation and other categories. Compared with seamless steel pipe, the cost of PE pipe is lower than 12%, and the service life of daily tasks is longer, which can reach 5Oa(generally 20a for seamless steel pipe). Not only that, its maintenance cost is also lower. However, in China, there are some categories of pipe standards and specifications are not perfect, which has a certain impact on the application and conduct of PE pipe. On the other hand, because galvanized steel pipe is slowly banned, PE pipe shows its advantages in the construction of power supply and other fields, and PE pipe also has irreplaceable shortcomings in the fields of natural gas, industrial production water supply and drainage, communication, farmland irrigation and other fields. However, in Changsheng area at home and abroad, PE pipe occupies a market share of 60% in power supply pipes, and the ownership of buried gas pipelines is also up to 90%. Not only that, China has established a very perfect construction specification in PE pipe level before.

Advantages of PE pipe:

① Good toughness. The fracture elongation of PE pipe can reach more than two times, not easy to break at will.

The low density and light weight make the transportation construction equipment more and more convenient. The pipe density is low (its density is 1/8 of that of ordinary steel pipe and 1/2 of that of glass steel pipe), and the transportation is easy, which enhances the rest of the construction personnel, makes the equipment convenient, enhances the construction time, and creates the target in a short time.

(3) Corrosion resistance, not easy to accumulate scale, especially in the mine transport sulfur content, calcium, aluminum ions of the material, very large extent to save the corrosion prevention and scale cleaning costs, the service life is far more than other pipes.

(4) The inner cavity of PE pipe is very polished, and the self-smoothness is excellent. The surface roughness of PE pipe is about 17% of that of ordinary steel pipe. In the case of tube passage in reverse, it can be transported 25% higher than that of metal pipe.

⑤ Antistatic, flame retardant grade. The antistatic agent and halogen-free flame retardant of the pipe are distributed in the polyethylene resin, and the anti-static and flame retardant properties have been made remarkable achievements for a long time.
