Steel Mesh Enhanced Water PE 80 HDPE Pipe Anti Cracking

Steel Mesh Enhanced PE Pipe

Process:

Steel Mesh Enhanced PE Pipe is a new kind of pressure pipe, was invented by HTIDC. It is made by combining metal-shaped steel reinforcement with polyethylene through extrusion technology. The steel mesh is made by continuously winding and welding the transverse wires spirally to the longitudinal wires to form a continuous tube-like mesh.


Properties:

1. Polyethylene Material

The stuffing material of Steel Mesh Enhanced PE Pipe and fitting is PE 80/PE100(piping class).
