Liansu HDPE double-wall corrugated pipe product features:
Liansu HDPE double-wall corrugated pipe is made from polyethylene as the main raw material, produced by a co-extrusion process involving inner and outer extruders, resulting in a smooth inner wall and a corrugated outer wall with a hollow layer in between. This unique design structure allows the double-wall corrugated pipe to save raw materials, exhibit high strength, high ring stiffness, lightweight, convenient transportation and construction, socket connection, low installation cost, good corrosion resistance, and pressure endurance. In addition, Liansu HDPE double-wall corrugated pipe is a flexible pipeline that requires no special construction for the ground, has good resistance to uneven ground settlement, and uses rubber ring seals for connections to achieve zero leakage. It has a service life of over 50 years and is specifically designed for underground sewage systems with large-diameter PE pipes.
