SN4/SN8 HDPE Flexible Drain Pipe

 a

Introduction to Flexible Drain Pipe:

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 Flexible Drain Pipe:

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 Flexible Drain Pipe:

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 Flexible Drain Pipe:

1. Civil engineering
2. Agricultural irrigation
3. Conveying system for sewage plant
4. Pre buried piping under highway
5. Ventilation piping for chemical industry and mine
6. Power telecommunication cable conduit
7. Bridge construction
