Dredging UHMW pipe

General description

The UHMW dredging pipe is very suitable for transferring slurry, soil. It is high resistance ability to wear, tear, water pressure and corrosion make the transfer more workable and safety. Made of Polymer polyethylene with the diameter from 25-800mm.

Advantage

  • High Resistant to wear and tear
  • High resistant to water pressure
  • High resistant to corrosion
  • Light weight and easy assembly with wildly working temperature
  • Safety and environmental protection with long life service
