HDPE DOUBLE WALL CORRUGATED PIPE

HDPE DOUBLE WALL CORRUGATED PIPE

HDPE Double wall corrugated pipes have a smooth – surfaced inner wall (colored yellow) surrounded by a profiled outer wall (colored black). The corrugated outer wall provides optimum strength under compressive loading form covering layers and traffic (High Ring Stiffness). The bright yellow color of the inner pipe also improves visibility in TV inspection, providing optimum, conditions for acceptance testing. Characteristics include:

  • High Protection against corrosion and resistance to chemicals
  • Easy Joining Methods
  • Easy Repair and Maintenance
  •  Long Service Life
  • Efficient Flow of Fluids
  • Flexible

Main Applications

HDPE Corrugated pipes are used in transporting liquids by gravity such as :

  1. Sewage Systems
  2. Rain drainage pipes
  3. Efficient water transportation system
  4. Industrial wastewater system.
