PE Large Diameter Winding Pipes Production Line

On the base of sufficiently absorbing European technique, our company successfully develops hollow-wall winding pipe production line, the produced pipes take HDPE as main material, firstly, the first extruder produces rectangle pipes, which enter winding shaping machine, at the same time, the second extruder ejects rubber bar, at last, they are pressed and compounded together. With even and smooth inner and outer walls, with specification of ?400-?2200mm, and according to different conditions, the rigidity is divided into four grades, the maximum achieves 16kn/m2, can adapt to acid and alkali liquids below 10%. This pipe with advantages of corrosion resistance, light weight, simple installation, high flux, long life(50 years), etc., can substitute the pipes made by high energy consumption materials(concrete, cast iron, eramics, etc. ), widely used in drainage pipelines of expressway, civic onstruction, residential quarter, playground, square, mines, agriculture, ulvert, bridge as well as other fields.
