SIFFO HDPE Steel Wire Mesh Reinforced Composite Pipe (SRTP Pipe or SRPE Pipe) is an advanced piping solution combining high-density polyethylene (HDPE) with a high-tensile steel wire mesh skeleton. It integrates the corrosion resistance of plastic pipes with the strength of metal pipes, widely used in municipal water supply/drainage, oil & gas transmission, chemical fluid transport, mining tailings disposal, and agricultural irrigation—especially for high-pressure, long-distance, and geologically challenging projects.
