Product Description

HDPE double wall corrugated pipe is a new type of pipe with annular outer wall and smooth inner wall. It was first developed in Germany in the early 1980s.After more than ten years of development and improvement, has developed from a single variety to a complete product series.At present in the production process and the use of technology has been very mature.Because of its excellent performance and relative economic cost, it has been widely used in developed countries such as Europe and America.In China, HDPE double wall bellows are in the phase of rising trend of promotion and application, all the technical indicators are up to the use standard.The inner walls of double-wall corrugated tubes are usually blue and black, and some brands use yellow.
