Strong resistance to external pressure: the outer wall is annular corrugated structure, which enhances the ring stiffness of the pipe and can resist soil load.
Smooth inner wall: large flow rate, not easy to scale, avoiding secondary pollution.
Easy connection: good interface sealing, corrosion resistance, zero leakage.
Long service life: underground use can reach more than 50 years.
Light weight: convenient construction, can reduce construction costs and shorten construction period.
Good low temperature resistance: normal operation in the temperature range of -40 degrees to 60 degrees.
Stable chemical properties: except for a few strong oxidants, most chemical media have no destructive effect on it.
