HDPE double wall corrugated pipe

Short Description:

The main raw material of HDPE double wall corrugated pipe is high density polyethylene, the pipe is extruded by the co-extrusion extruder from the inside and outside respectively, inner wall is smooth and outer wall is trapezoidal.
There is a hollow layer between the inner and outer wall. Product has variety of advantages like high ring stiffness, strength, light weight, noise damping, high UV stability, long life and good bending, anti-pressure, high impact strength and so on. It can be used in the poor geological sections, it is the ideal replacement for traditional sewage drainage pipes.
