good flexibility: the safe operation temperature of PE pipe is -20° C to +40° C. Compared with steel pipe, its good flexibility can avoid pipe breakage due to external factors such as stratum subsidence.

Aging resistance, long service life: 2.0%-2.5% of the uniform distribution of carbon black can effectively resist oxidation caused by pipe aging, and the pipe is not subject to external corrosion of acids, alkalis and salts, no scaling on the inner wall, to ensure the smooth flow of gas transmission, so that the service life of PE pipe can reach 50 years.

Safe and reliable connection: adopting heat fusion butt joint or electric fusion connection, forming a homogeneous connection system, tight connection, light weight of the pipe, reducing the construction intensity and cost.
