HDPE Double Wall Corrugated Pipe

 

 

Introduction to Corrugated Pipe Fittings for Drainage:

 

HDPE double wall corrugated pipes (double-layer twisted pipes) are one mould profile two layer extrudings. Applies to rain water drainage, sewage drainage in residential district, or pollutant and exhaust gas discharge as well as sewage drainage for mine industry, or organic pollutants drainage from people's life, agricultural drainage, low pressure irrigation and coalmine ventilation.

 

Features of Corrugated Pipe Fittings for Drainage:

1. High tensile strength, compressive resistance and well impact resistance;
2. Anti-uneven settling property, and can be applicable to soft clay shifting sand foundation;
3. Convenient for connection with non-breakable joint.
4. Smooth inner wall, high friction resistance, large quantity of water flowing.
5. Decay resistance, "green pipe",  avoid secondary pollution.
6. Light weight, easy for carrying and transporting, convenient for construction with low comprehensive cost.

 

Advantages of  Corrugated Pipe Fittings for Drainage  :

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 joint;
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.

  

Application of Corrugated Pipe Fittings for Drainage:
