HDPE pressure Pipe Extrusion Line is a pipe extrusion line developed by HSD company through assimilate and master technology introduced from abroad. It is applicable for extrusion of PE, PP, PB, PERT, ABS etc. This PE pipe production line can instead extrusion line imported from abroad.
This pipe extrusion line mainly includes single screw extruder, molds, vacuum calibrating water tank, spray water cooling tank, haul-off machine, cutting machine and bracket.
Plastic Pipes produced by this line have excellent stiffness, flexibility, high mechanical strength, resistance of environmental stress cracks, resistance to creep deformation, heat-linkage and so on. It has become the first choice for the city gas pipe, water supply pipe, foundation pipe, landfill collection pipe, watermain, geothermal heating etc.
