High-density polyethylene double-wall corrugated pipe was developed by Germany. 20 Century 80 A new type of pipe, developed in the early years, features a circular outer wall and a smooth inner wall. After more than a decade of development and refinement, this product has evolved from a single variety into a complete product line. Currently, both its manufacturing technology and application technology have reached a high level of maturity. Thanks to its outstanding performance and relatively low cost, it has been widely adopted and applied in developed countries such as those in Europe and the United States. In China, the promotion and application of high-density polyethylene double-wall corrugated pipes are currently on the rise, and all technical indicators have met the required standards for use.
