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).

2. The pressure reduction factors shall apply to pipes to be used at different temperatures

(Conveying water lower than 20℃ does not play adverse effects on the performance of the pipe. The working pressure at higher temperature shall be obtained by multiplying the nominal pressure given in table 1, with the pressure reduction factors given as below.)
