HDPE double wall spiral winding tank production extrusion machines:1).Hollow structural wall spiral pipe features:
DN200-4500mm HDPE hollow wall winding pipe uses high-density polyethylene as the main raw material, adopts spirally winding forming technology, the inner and outer pipe walls are flat, ring stiffness classes from SN2 to SN16, frictional resistance is small,acid-resistant, alkali-resistant, anti-corrosion, non-toxic, compressive, not easy to age, and the service life is more than 50 years. The construction is convenient and the construction cost is low. In china, it has become a substitute for cement pipes, cast iron pipes, and glass pipes.
2)Extrusion line include: Conical Twin screw extruder or High speed single screw Extruder,Cladding Co-extrusion die, Vacuum calibration water tank, Cooling water tank, Hauling machine,Spiral forming unit,Automatic Cutter and Automatic Stacker .
3)Application: construction of main network of household sewage treatment system, rainwater treatment system, industrial wastewater treatment system; production of sewage wells, storage tanks, cable wells.
