        1. Steel framed polyethylene(PE) composite pipe

          Steel framed polyethylene(PE) composite pipe uses high-strength copper coated steel with mesh structure as skeleton and high or medium density polythene as stuffing material, and its structure in production line though continuous and separately extruding and compound technique.

          technical standard

          The production and construction of products strictly implement international national standards.

          Highly paid proprietary technology

          Steel framed polyethylene(PE) composite pipe uses high-strength copper coated steel with mesh structure as skeleton and high or medium density polythene as stuffing material, and its structure in production line though continuous and separately extruding and compound technique.

          industrial standard

          The steel skeleton polyethylene plastic composite pipe has established a complete series of standards.

          performance advantage

          use the high quality PE materials

          Creep resistance, excellent hydraulic performance, abrasion resistance ,corrosion resistance, sanitation and environmental-friendly, the service life can be over 50 years though.

          Performance advantages

          It is stable to composite steel and plastic for steel framed polyethylene plastic pipe, hardness with softness, creep resistance, impact resistance,rapid crack propagation resistance,lower coefficient of thermal expansion,good quality of Traceability,easy installation.

          production technique

          Steel skeleton of polyethylene plastic pipe USES continuous winding Angle welding net frame, plastic melt extrusion and frame synchronization composite molding process Which with high quality low carbon steel wire for enhanced phase, polyethylene (PE) as the matrix, through molding machine wire welding into the net, and the molten polyethylene composite extrusion in the compound nose, on the production line continuous composite molding, cooling traction incision sealing, get straight tube products

          CONNECTION TYPE

          hot melt connection

          The steel framework polyethylene plastic composite pipe is used to absorb the mature connection technology and experience of traditional plastic and metal tube, and can be connected by electric fusion connection and live flange connection.

          flanged joint

          The steel framework polyethylene plastic composite pipe and other metal pure PE tube valves and gauges are connected by flange connection.

          built-up connection

          The connection of electric welding and flange connection of the composite pipe is higher than that of the pipe.
