China UPVC Double Wall Corrugated Pipe Extrusion Line

HDPE/PVC/PP double wall cor

rugated pipe production line is used to produce plastic double wall corrugated pipe (DWC pipe).

For HDPE pipe, high efficient single screwextruder is applicable.
For PVC pipe, conical twin screw extruder or parallel twin screw extruder are more suitable.
Forming system consists mould and corrugator.Mold blocks can be easily changed and they have air or water cooling system.
The belling process is on line.High precision cutting can be guaranteed by cutting machine.The production line can be also be equipped with Simens PLC system.

Technology and Service:

1.Seller supply full set of technical document, cutter and other full document (write in English).

2.Seller supply training for buyer's staff until buyer can produce the eligible production independently.

3. Seller is responsible for installing, testing, adjusting and commissioning the machines in buyer's factory.

4.Buyer should pay the expense for our engineers including for our engineer including round-

way tickets, inland traffic, lodging and boarding fee when the machine is installed, tested and maintained.

5. Seller will go to install machines after the machine is arrived at buyer and buyer will have prepared all conditions (including power, water, compress air, tools and materials for producing pipe, etc) for installing and testing these machines. Buyer should pay 100USD/day.
