HDPE Double-wall Corrugated Pipe 2015 Hot Sell China No. 1 Brand Less (Liansu) Group
Specifications
HDPE Double-wall Corrugated Pipe:good compression resistance,corrosion resistance&impact resistance;high flow capacity;HDPE Double-wall Corrugated Pipe:
Liansu HDPE double wall corrugated pipe is conformed to prEN 13476-1, the ring stiffness rates are SN4 and SN8.
(Remark: SN is Nominal Ring Stiffness, which relesctis the ability that a pipe resists the deformation due to an external load. Stiffness classes are identified by an SN number which higher number indicates greater resistance to deflection)
Product advantages:
1. High density, good compression resistance and good impact resistance;
2. Good resistance of asymmetrical bedding, available being buried in the mollisol and quicksand;
3. Rubber ring connection, easy but no leakage in the joit;
4. Smooth interior wall and low friction, high flow capacity;
5. Good corrosion resistance and no environment pollution;
6. Light weight, easily transport and install, low construction cost;
7. Application: municipal sewage; rainwater discharge; floodwaters drainage; irrigation; ventilation for mine and buildings; industrial waste discharge.
