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. Our machine can process wide range of material, including HDPE, PP, PVC, etc.
Our double wall corrugated pipe extrusion line can produce from inner diameter of 63mm to 800mm.

PVC Double Wall Corrugated Pipe Making Machine Components:
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 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.
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..
Cooling tank is used to cool pipe .
Cutter.
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.
