Introduction:
HDPE Double wall corrugated pipe is mainly used for water drainage system, sewage outlet, insulation o wire and cable, heat supply engineering in high building and undergroud building.It is a fully computer controlled line.It features high and stable output capacity, and highly automatic operation.For HDPE, you can choose high efficient conical twin screw extruder.Forming system consists mould and corrugator.Mould 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 also be equipped with PLC system.

Structural feature:
1, equipped with two high-efficient conical twin screw extruders and notching machine barrel to ensure effective extrusion of different materials for two walls.
2, highly effective cooling system can ensure high speed production in continuity.
3, nitrogen treated moulds and adjustable wall thickness device can ensure production with different materials and hg degree.
4, corrugated moulds are made of precisely casted special alloys which can provide high precision and pressure resistance as well as good heat elimination effects.
5, advanced pipe end expansion functions reduce much investment cost and enhance productive force.
6, the line adopts advanced Siemens PLC control system and large liquid crystal screen handling system, which realizes high automation, reliable operation and easy handling.
