DWC pipe line
HDPE double wall corrugated pipe is a new type of lightweight pipe made of high density polyethylene. It has the characteristics of light weight, high pressure resistance, good toughness, and long life. 
Compared with this, the cost is greatly reduced. And because of convenient and reliable connection, it is widely used at home and abroad. instead of concrete pipe and cast iron pipe.

Appearance: black.
Performance characteristics:
1. Unique structure, high strength, compression and impact resistance.
2. The inner wall is smooth, frictional, and the over-flow is large.
3. Convenient connection, well sealed joint, no leakage.
4. Light weight, fast construction and reduced costs.
5. The service life of buried ground is more than 50 years.
6, polyethylene is a hydrocarbon polymer, the molecule is non-polar, resistant to acid and alkali corrosion.
7. The raw materials are environmentally friendly materials, non-toxic, non-corrosive, non-scaling, and can be recycled and reused.
8. The applicable temperature range is wide, the pipeline does not break in the environment of -60 ℃, and the maximum temperature of the conveying medium is 60 ℃.
9. The comprehensive engineering cost is basically the same as that of concrete, and the operating cost is low.
10. No foundation is required if the soil is good.

Hdpe double wall corrugated pipe can be transported by various means of transportation.
During transportation, loading and unloading, no drop, impact, heavy pressure, prolonged exposure or close to heat source is allowed. Mixed transportation with toxic and hazardous substances is not allowed. 
The disc-shaped perforated tube cannot be transported flat.
HDPE double wall corrugated pipe should be stored in a dry room at room temperature. Straight pipes should be laid flat and the stacking height should not exceed 2 m. Disassembled and coiled perforated tubes can be laid flat, but heavy pressure or squeezing should be avoided.
HDPE double wall corrugated pipes are not allowed to be mixed with toxic and hazardous substances.
The storage period shall not exceed 2 years from the date of production. .
