Anti-corrosion
Good connection security
Pipes are mainly connected by heat fusion butt joints and electrofusion, realizing the integration of joints and pipe materials, and the strength of the interface is higher than the strength of the pipe body itself.
High Flexibility
Pipe elongation at break ≥ 500%, with high flexibility, very strong ability to use the uneven settlement of the soil, superior seismic performance.
Good impact resistance
Under the low-temperature environment, -20 ºC -40 ºC can be used normally, the external impact is not easy to crack, cracks and other damage.
Good cracking resistance
Excellent resistance to rapid crack propagation (RCP) and slow crack growth (SCG) transfer resistance, which effectively prevents pipe cracking and crack propagation in low-temperature areas and in case of installation damage.
Low friction coefficient
Smooth inner wall, smooth surface and non-adhesive properties ensure pipeline conveying capacity and also reduce pressure loss in the pipeline.
