PE Hollow Wall Winding Pipe Extrusion Line

Hollow wall winding pipe is mainly used for sewage system, same as double wall corrugated pipe. Compared with double wall corrugated pipe, it have advantages of low machine investment cost and larger pipe diameter.

Our PE hollow winding pipe extrusion line can process several kinds of material, including HDPE, PP, etc, size from minimum 200mm to 3200mm with single layer or multi-layer.

Changing some parts can produce different shape of pipe or profile to form different kinds of spiral pipe.

The first extruder produce rectangular pipe into winding forming machine , the second extruder produce plastic bar, then the plastic bar is pressed on the rectangular pipe and winding pipe comes out. Outside and inside of winding pipe is smooth and neat.

It adopts spiral die head and two extruder charging, realizing spiral rotational forming.

The advanced PLC computer control system makes it easy to operate. It’s stable and reliable.

Main machines of extrusion line

Extruder

Adopt L/D ratio 38:1 screw for virgin material. Adopt L/D 33:1 screw for recycled material. We also have choice of twin screw and barrel for other material such PP powder, etc. Provide suitable extruder for different customer requirements.

Extrusion Die Head

Extrusion die head apply spiral structure
Ensure melt temperature uniformity, thoroughly eliminate confluence seam and reduce flaws such as bubble, black spot, unsmooth inside wall, caused by too high temperature.

Vacuum Tank

Vacuum tank is used to shape and cool pipe, so as to reach standard pipe size. We use double-chamber structure. First chamber is in short length, with pipe soak into water to ensure very strong cooling and vacuum function. As calibrator is placed in the front of first chamber and pipe shape is formed mainly by calibrator, this design can ensure quick and better forming and cooling of pipe.

Forming Machine

Winding machine is used to wind square pipe and attach them together to form spiral pipe. It is adjustable to produce different spiral pipe sizes, also winding angel is adjustable for square pipe in different width.
With effective water cooling.
Supporter structure are similar with foreign advanced machine and convenient to observe spray effect.

Cutter

Cutter controlled by Siemens PLC with fully automatic cutting process. Can customize cutting length.

Stacker

To support pipes. With rubber support roller, roller will rotate along with the pipe.
