Vertical hollow wall steel-plastic composite winding pipe with you to understand the double wall bellows!

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, fast construction and long life, etc. Its excellent wall structure design greatly reduces the cost compared with pipes of other structures. And because the connection is convenient and reliable, it has been widely used at home and abroad. Lots of replacement concrete pipe and cast iron pipe.

What are the characteristics of double-wall bellows?

1, strong resistance to external pressure

Because the outer wall of the double-wall bellows has a circular corrugated structure, the double-wall bellows have a strong ability to resist external pressure.

2, low project cost

Compared with other wall pipes of the same material, the cost of this double-wall bellows is relatively low.

3, convenient construction

It is said that the double-wall bellows are relatively light in weight and convenient in handling, so the construction is relatively convenient and the maintenance is relatively simple, so in the case of tight construction period, the advantages of double-wall bellows will be more obvious.

4, small friction coefficient

Compared with pipes of the same caliber, double-wall bellows have larger water flow and smaller friction coefficient.

5. Low temperature resistance and impact resistance

Double wall bellows low temperature resistance, good impact resistance, even below minus 30 degrees, do not take special protective measures, winter construction is convenient.

6, good chemical stability

The vertical hollow wall steel-plastic composite winding pipe tells you that the double-wall corrugated pipe has good chemical stability, even under poor environmental conditions of soil and electricity, it will not be damaged, no scaling, and the circulation area will not decrease with the increase of running time.

7, long service life

The service life of the double-wall bellows is long, and the service life can reach more than 50 years under the condition of not being subjected to ultraviolet light.

8, excellent wear resistance

Double-wall corrugated pipe has a strong wear resistance, several times higher than the steel pipe.

Scope of application

1, municipal drainage, sewage pipeline system engineering;

2, apartments, residential areas buried underground drainage sewage;

3, highway buried pipeline, golf course underground seepage pipe network;

4, irrigation irrigation, waterlogging and other water conservancy projects;

5, chemical industry, mining for fluid transport and ventilation;

6, underground pipeline protection sleeve and communication cable protection sleeve, etc.
