1) Introduction: single-wall corrugated pipe extrusion line can be used to produce single-wall corrugated pipes of PE, PP, PVC, EVA continuously as well as PA corrugated pipes
2) Characteristic: Plastic single-wall corrugated pipes have features of high temperature resistance, resistant to corrosion and abrasion, high intensity, good flexibility, etc .
3) APPLICATION: They are widely used in fields of auto wire, electric thread-passing pipes, circuit of machine tool, protective pipes of lamps and lanterns wire, tubes of air conditioner and washing machine, etc. The pipes from this production line are widely used in washing machine tubes and sink drain-pipes.
  SJ series plastic single-wall corrugated pipe production line developed by our company adopts gears to run modules and templates. The products have water circulating cooling and air cooling system, which ensures high-speed molding, even corrugation, smooth inner and outer pipe wall.

1. forming machine is a closed type structure and provide internal pressure and vacuum forming
2. forming module is moving in a tunnel
3. forming module is made of hard alloy steel and anti-corrosion , abrasion
4. no any connection between forming module then reduce time of change module
