Specializing in the production of PP pipes, steel lined composite pipes, HDPE pipes, HDPE dredging pipes, UHMW-PE pipes, PP boards, PE boards, UHMW-PE boards, as well as required accessories and valves. 1. PP pipe (polypropylene pipe): Polypropylene material is extruded into shape through a certain process. 2. Steel lined composite pipe: Steel pipe is used as the matrix, lined with various thermoplastic materials (polypropylene, polyethylene, modified polyethylene, polytetrafluoroethylene, etc.), which are cold drawn composite or integral rotational molding, injection molding, etc. 3. HDPE pipe (high-density polyethylene pipe): Made of HDPE resin using advanced production processes and technologies, and formed by hot extrusion molding. 4. HDPE dredging pipe (high-density polyethylene dredging pipe): Made of high molecular weight polyethylene HDPE large-diameter dredging pipe material, it is a high-strength plastic sand transport specialized pipe produced. 5. UHMW-PE pipe (referred t...
