High density polyethylene (HDPE) corrugated pipe is a pipe with a structured outer layer profile and smooth inner wall. It was first developed in Germany in the early 1980s. After years of development and improvement, it has evolved from a single variety to a complete product series. Today, it represents the most advanced production technology in its category.
Because of its excellent performance and relative economic cost, it has been greatly promoted and applied in developed countries throughout Europe and the United States. In China, the promotion and application of HDPE double wall corrugated pipes are on an upward trend, with all technical indicators meeting application standards. The inner wall of double wall corrugated pipes is usually blue and black, though some brands use yellow.
