The PE gas pipe must meet safety standards and regulations.

1, easy to fuse - electric melting or hot melting can form a completely closed anti-seepage system.

2, easy to install and handle - light weight, density is only 1/8 of steel.

3, strong flexibility - can be wound, can be used for deep ditch external welding, can make the pipe along the direction of deep ditch winding, reduce the number of joints, can resist ground movement (earthquake and mining soil depth drop).

4, resistance to internal and external and microbial erosion, with good hydraulic resistance, the inner wall smooth flow resistance is small, welding pollution is small, simple process, convenient construction; Weak electrical conductivity; Resistant to chemical corrosion; Strong environmental adaptability; Strong air tightness, low gas permeability, low maintenance costs, obvious economic advantages, more than 50 years of service life (low depreciation).
