After more than ten years of development and improvement, it has developed from a single variety to a complete product series. It is very mature in production technology and application technology. Due to its excellent performance and relatively economical cost, it has been greatly promoted and applied in developed countries such as Europe and the United States. HDPE 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.
