HDPE double wall corrugated pipe
HDPE double-wall bellows, referred to as PE bellows, were first developed in Germany in the early 1980s. After more than ten years of development and improvement, it has developed from a single variety to a complete product series. In the production process and the use of technology has been very mature. Due to its excellent performance and relatively economic cost, it has been greatly promoted and applied in developed countries such as Europe and the United States. 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.
Performance characteristics
peculiarity
1, unique product structure, strong pressure resistance;
2, the inner wall is smooth, the overflow is large;
3, the product connection is convenient, the interface is sealed well, corrosion resistance, zero leakage, no scaling, avoid secondary pollution, is the ideal "green pipe";
4, the product has good flexural performance, can adapt to the uneven settlement of soil;
5, long service life, buried use can reach more than 50 years;
6, light weight, convenient construction, can reduce construction costs, shorten the construction period;
7, at a speed of 15 feet/second, the wear resistance is 3 to 5 times higher than that of ordinary or fine-grained steel pipes.
