High-density polyethylene (HDPE) double-wall corrugated pipe bellows short historical review PE HDPE double wall corrugated pipe is a smooth outer wall and an inner wall of the ring structure of the new pipe, first developed in the early 1980s success in Germany. After ten years of development and improvement, has grown from a single species to the complete product line. Currently in production processes and the use of technology has been very mature. Because of its excellent performance and relatively economical cost, in Europe and other developed countries have been greatly promoted and applied. Features: 1, the unique structure, high strength, compressive impact resistance. 2, wall smooth, friction, excessive flow 3, easy connection, joints sealed, no leakage. 4, light weight, quick construction, and reduce costs. 5, the buried life of five years or more 6, polyethylene are hydrocarbon polymers, molecular polarity, acid corrosion. 7, the raw material for green materials, non-toxic, non-corrosive, non-scaling, recyclable. 8, suitable temperature range, -60 ℃ environment does not break in the pipeline, the maximum temperature of the transmission medium is 60 ℃. 9, comprehensive and concrete construction cost is roughly equal, low operating costs. 10, no foundation soil under good conditions.
