Double wall corugated pipe making machine (horizontal)

Short Description:

Double wall corrugated pipe is mature product which has the advantage of low weight, low cost, anti-corrosion, good ring stiffness and flexibility. Our company has developed PE double wall corrugated pipe extrusion line for more than 20 years. We have the whole series of double wall corrugated pipe machine: horizontal type, vertical type and shuttle type.

Different from the vertical type of corrugated pipe line, the horizontal type of corrugator is much easy in operation and can achieve high production speed.  The whole production line is centralized to be controlled by PLC control system.

Our double wall corrugated pipe extrusion line can produce from inner diameter of 63mm to 400mm.

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 PVC powder, PP powder, etc. Provide suitable extruder for different customer requirements.

Die Head and Calibration Sleeve

Both outer layer and inner layer are extruded inside die head. Each material flow channel inside die head is placed evenly. Each channel is after heat treatment and mirror polishing to ensure material flow smoothly. Also die head provides compressed air between both layer.

Calibration sleeve is used to cool inner layer to form smooth and flat pipe inside. Pressure water flows inside calibration sleeve to have good cooling effect. Vacuum is created on calibration sleeve surface when producing big diameter pipe, ensure inner pipe roundness.


Corrugator and Corrugated Mould

Corrugator is used to place and move corrugated mould. Vacuum is created to absorb outer layer into corrugated mould to form corrugate shape. By moving corrugated mould, pipe is also pulled out from corrugator.

Cooling tank

Tank adopts stainless steel with PVC window

Two sets of filter system for non-stop cleaning

Cooling tank is used to cool pipe further.

4---cooling tank


Cutter controlled by Siemens PLC, double knife cutter. Equipped with precise inspection device ensures the cutter accurately placing at the correct position of double wall corrugated pipe. Whole cutting process is accurate and fully automatic.


Pneumatic overturn with stainless steel, to prevent scratch of pipe surface

To support and unload pipes. Length of stacker can be customized.
