Shanghai Metal Corporation is a leading Steel-Plastic Composite Pipe manufacturer and supplier.
Steel-Plastic Composite Pipe is a steel pipe based product with plastic anticorrosive coating on its inner or outer surface or inner and outer surface. It’s also known as Steel Pipes of Complex Plastic.
The steel plastic composite pipe is made of seamless steel pipe and welded steel pipe. The inner wall is coated with high adhesion, anticorrosive, food grade hygienic polyethylene powder coating or epoxy resin coating. The water supply galvanized internal coated plastic composite steel pipe, which is made of pretreatment, preheating, internal coating, leveling and post-treatment processes, is an upgraded product of the traditional galvanized pipe. The steel plastic composite pipe is generally connected by thread, groove and flange.

4. The connection method with pipe fittings can adopt stranded wire, socket, flange, groove, welding, etc., various ways, save labor and effort
5. The difference in thermal expansion coefficient of the connection part with the pipe is small, safer and more reliable
6. Reasonable price-performance ratio, low overall cost, more economical than copper pipes and stainless steel pipes
Technical Information of Steel Plastic Composite Pipe：
1. Processing method:
Steel-Plastic Composite Pipes are mainly divided into three categories: Steel Pipes of Lining Plastic, Coating Plastic Steel Pipe, and External Coating Plastic Steel Pipe.
Steel Pipes of Lining Plastic refers to the composite pipe lined with thin-walled plastic pipe on the inner wall of the steel pipe.
Coating Plastic Steel Pipe refers to the composite pipe which melts a layer of plastic powder inside or outside the steel pipe.
External Coating Plastic Steel Pipe refers to the composite pipe covered with plastic melt adhesive and melt plastic layer on the outer surface of steel pipe.
