High-density polyethylene (HDPE) double wall corrugated pipe, a new type of pipe with a ring-like structure of the outer wall and smooth inner wall, was first developed successfully in Germany in the early 80s.Due to its excellent performance and relatively economical cost, it has been greatly promoted and applied in countries all over the world.
Double wall corrugated pipe inner wall color usually has blue and black, some brands will use yellow inner wall.


Benefits Of HDPE Double Wall Corrugated Pipe

High density polyethylene (HDPE) has excellent chemical stability, aging resistance and resistance to environmental stress cracking performance. HDPE double wall corrugated pipe produced from its raw materials belongs to the flexible pipe. Its main advantages are as follows.

  • -Rational structure and beautiful appearance
  • -Temperature resistance -40℃-60℃
  • -Low resistance, high flow rate
  • -Flame retardant force -Long service life
  • -Reliable sanitary performance
  • -Integrated low cost -Acid and alkali resistance and corrosion resistance
  • -High strength, strong anti-seismic performance
  • -Energy saving and consumption reduction
  • -Easy to install and transport
