HDPE Double Wall Corrugated Pipe

HDPE Double wall corrugated pipe combines a corrugated outer wall for exceptional strength and a smooth inner wall for outstanding hydraulic characteristics.

PRODUCT DESCRIPTION

The HDPE double-layer corrugated pipe has a smooth surface inner wall (yellow), surrounded by a molded outer wall (black). The corrugated outer wall has the best strength under high pressure (high ring stiffness). The bright yellow color of the inner tube also improves the visibility of the TV inspection and provides the best conditions for the acceptance test.
