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.
