PP PE PVC Double Wall Corrugated Pipe Machine , dwc Pipe Manufacturing Machine With Single Screw Extruder
Quick detial of corrugated pipe machine:
1. The inner and outer walls of the composite reinforced HPVC double wall corrugated pipe are hollow ring structure, which makes full use of the I-steel structure principle to improve the section inertia rectangle and high ring stiffness.
2. The product has the advantages of high strength, good toughness and light weight. Products are used in excavation projects, can replace MPP single wall corrugated pipe, CPVC electric cable pipe, PVC-U communication pipe and other pipes.
Description of double wall corrugated pipe machine:
1. Extruder: high efficient screw, hard gear surface gearbox, uniformed raw material heating, good plasticization, high extrusion speed.
2. Corrugation forming machine: closed structure, module link in the overall closure base does round-trip running in the running tunnels.
3. Forming modules: it is made of hard steel, dealed with a rigorous use of CNC finishing materials produced to ensure the hardness and precision of the molding modules. These modules are easy and convenient to change
4. Coiler :Single position or double position with torque motor.
5. Electrical parts: ABB inverter, Schneider contactor, RKC thermo controllers etc.
