HDPE Double Wall Corrugated Pipes

High-density polyethylene (HDPE) double-wall corrugated pipe is a new type of pipe with smooth inner wall and ring-shaped outer wall structure. It is an environmentally friendly product that combines the corrosion resistance of plastic with the toughness of steel. It has strong pressure bearing capacity, lightweight, simple installation, safety and reliability, good sealing performance, and strong corrosion resistance.

HDPE Double Wall Corrugated Pipes can be widely used in municipal engineering drainage and sewage engineering; various industrial and agricultural water delivery and irrigation projects; road project: such as railways, highways, stadiums, etc.

HDPE Double Wall Corrugated Pipes Advantages

1. HDPE double wall corrugated pipe is very convenient for handling &installation with much lighter weight.

2. HDPE double wall corrugated pipe has excellent acid and alkali resistance, corrosion resistance which is suitable for chemical industry.

3. Fluid resistance of HDPE double wall corrugated pipe is small and the roughness coefficient is only 0.009, which effectively improve the hydraulic condition of the pipe network and it greatly reduces system operation cost.

4. Strong resistance to external pressure: The product has unique structure and the ring stiffness is up to SN12.5, with super rigid.

5. HDPE Double wall corrugated pipe connections is quite convenient which could save the construction engineering cost.

6. HDPE double wall corrugated pipe is sanitary. The dissolution test confirms that it does not affect the water quality, suitable for popularization and application in large areas.
