Technical process:
Raw materials→Mixing→Vacuum feeding→Material drying→Single screw extrusion →Calibration→Spray cooling→traction→Single screw glue extrusion →Winding and forming→water cooling→cutter→pipe bracket→inspecting &packing.

The complete production line includes two parts:

1.The first part is 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. The second part is Spiral forming line to form and weld the big pipe.
Single Screw Extruder
Die Head
Spiral forming unit
Cutter
Bracket 

High-efficiency single screw extruder
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.
