Detailed Product Description

Large diameter steel reinforced polyethylene spiral corrugated pipe is developed
by Goldstone based on the normal polyethylene corrugated pipe.

The innovation reinforced corrugated pipe provide the steel reinforced structure to definitely increase the ring stiffness of the corrugated pipe;In the mean time, the weight of the pipe has been obviously reduced.The pipe diameter could be ranged from 600mm to 2000mm, which gives the large diameter pipe the better ring stiffness more than SN8.

The pipe has innovated three layers wall structure: The steel reinforced layer is
in the middle structure to provide the high stiffness, and either the inner layer
or outer layer is formed by high-density polyethylene that protects the pipe  out of corrosion.

And there is a super bond medium between steel and polyethylene which integrate them into one piece.
