The complete production line includes two parts:

1. PE Pipe Extrusion Line - to extrude the PE/PP Square Shaped Pipe (according to customers' requirements)
   • Single Screw Extruder
   • Die Head (mold and mandrill)
   • Calibrator
   • Vacuum calibration & cooling Tank
   • Spray Cooling Tank
   • Haul-off
2. Spiral Forming Line - to form and weld the big pipe
   • Single Screw Extruder
   • Die Head
   • Spiral forming unit
   • Cutter
   • Bracket

The extruder is equipped with the forced water-cooling feeding section and slotted barrel, which makes the power consumption of the main drive motor greatly reduced.
