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:
HDPE Corrugated pipes are used in transporting liquids by gravity such as :
Manufactures according to DIN 16961 – 16566.

Using electrometric seal ring spigot jointing, the connection and installation is as follows:
1. Clean pipe surface
2. Install rubber ring
3. Spread Lubricant
4. Connect Pipe
5. Insert pipe
