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).
