HDPE Double-Wall Corrugated Pipe

 

 

HDPE Double-wall Corrugated pipe for drainage features:

 

1.Non-toxic: no heavy metal additives, would not be covered with dirt or contaminated by bacterium.

 

2.Corrosion Resistant: resist to chemicals and chemical corrosion.

 

3.Lower Installation Costs: light weight, and it can reduce installation costs by as much as 50% over steel pipeline system.

 

4.Higher Flow Capacity: smooth interior walls result in lower pressure loss and higher volume than steel pipes.

 

5.Recycled and Environment-friendly.

 

 

HDPE Double-wall Corrugated pipe for drainage Advantages

1. Chemical stability:

 

As lack of polarity in the molecules, the HDPE material has good performance in chemical stability. In spite of

 

few oxidants, most of the chemical medium can not damage. Corrosion resistant and anti stains. The interior

 

flow capacity not be reduced after long time usage. HDPE pipe is a kind of environmental product.

 

2. Formidable joint strength:

 

Mainly refer to the thermal welding. For eg. Few joints, no leak.

 

3. Convenient installation:

 

Light weight and ease of installation. Can reduce installation cost, especially in bad environment.

4. Higher flow capacity:

 

Smooth interior walls result in lower pressure loss and higher volume.

 

5. Better wrap and bend ability:

 

The vertical allowable bending benefits the construction on fluctuant earth surface.

 

6. Low temperature preservation:

 

Anti-embrittlement temperature reaches -70oC,and under common low temperature (-30 oC), no need to adopt special defending

 

 or protecting. Convenient to install in winter. In the mean time, the pressure resistant test can stand 2.5 times nominal pressure by

 

water hammer.

 

7. Corrosion resistant:

 

Germany lab ever proofs anti-corrosion of the HDPE material is several times than that of copper.

8. Longevity:

 

More than 50 years under proper use.
