UHMW-PE composite pipe （UHMWPE Mining pipe、UHMWPE Dredge Pipe、UHMWPE Roller Pipe） is composed of UHMW-PE pipe and carbon steel pipe by scientific technology. It is characterized in that a steel pipe with a flange as an outer layer of a reinforcing protective layer, and UHMW-PE is used as an inner layer of a base pipe material, and the two characteristics are combined into one.
