Double-wall corrugated pipe is a new type of light-weight pipe made of high-density polyethylene. It has the characteristics of light weight, high pressure resistance, good toughness, fast construction and long life. Its excellent design of pipe wall structure is different from other structures. Compared with pipes, the cost is greatly reduced. And because of the convenient and reliable connection, it is widely used at home and abroad. Substantially replace concrete pipes and cast iron pipes.

1. Unique product structure and strong pressure resistance;

2. The inner wall is smooth and the excess flow is large;

3. The product is easy to connect, the interface is well sealed, corrosion-resistant, zero leakage, no scaling, avoid secondary pollution, is the ideal "green pipe";

4. The product has good deflection performance and can adapt to the uneven settlement of the soil;

5. Long service life, can be used underground for more than 50 years;

6. The product has light weight and convenient construction, which can reduce the construction cost and shorten the construction period;

7. At a speed of 15 feet per second, the wear resistance is 3 to 5 times higher than that of ordinary or fine-grained steel pipes.
