Perforated steel reinforced polyethylen pipe (SRPE) technology is developed by Goldstone since 2000. The main body of this composite pipe is a steel welding pipe, with many perforated holes on it. and both the inner and outer layer of the pipe is the extruded polyethylene, and these two plastic layers are connected through those holes.

The steel welded pipe can increase the plastic pipe strength significantly, while coated by plastic gives the welded steel pipe a perfect anti-corrosive property to prolong the steel pipe service life. So this composite is a kind of idea industry pipe, which features stiffness, rigid as steel pipe and anti corrosive, long life like the plastic pipe.
