1) . High-density polyethylene (HDPE) Hollow-wall Spiral Winding Pipe machines features: HDPE spiral wound 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.
Extrusion line include: vacuum feeding machine → hopper dryer → single screw extruder (for square pipe)
→ mold → vacuum tank → cooling tank→ single screw extruder (for glue)
→ spiral winding machine→ cutting machine→ stacker

3) Application:
it can be used for approximate 50 years and has many advantages such as low cost assembly and easy operation, with standing pressure, corrosion resistant such as acid, alkali and salt etc. It is becoming as a replacement of cement pipe and cast iron pipe nowadays. It is being widely used as sewage and drainage pipe.
construction of main network of household sewage treatment system, rainwater treatment system, industrial wastewater treatment system; production of sewage wells, storage tanks, cable wells.
