Steel reinforced polyethylene pipe perforated steel rigid composite pipe
Perforated steel composite plastic pipe (PSP) technology was developed by Goldstone in 2001. Pipe is reinforced by a steel welding tube with perforation on its body. The inner and outer plastic layers are locked through those holes. PSP pipe is as rigid as steel pipe and also has good corrosive proof ability like plastic pipe. It can by applied in many industry fields working in very difficult conditions.
1. Cost saving
2. Thermo expansion/shrinkage coefficient is the same
3. Rigid pipe suitable for cross-over pipe
4. Stable pipe structure, no separation
