What is the difference between high-density PVC double wall corrugated pipe and steel skeleton PE composite pipe?
HDPE double wall bellows, referred to as PE bellows, was first developed in Germany in the early 80s. After more than 10 years of development and improvement, it has developed from a single variety to a complete product line. In the production process and the use of technology has been very mature. Because of its excellent performance and relatively economic cost, it has been widely promoted and applied in developed countries, such as Europe and america.
HDPE double wall corrugated pipe has excellent chemical stability, aging resistance and environmental stress cracking performance. The HDPE double wall corrugated pipe produced by the raw material belongs to the flexible pipe. Its performance is as follows:Strong resistance to external pressureThe outer wall of an annular corrugated structure, greatly enhance the ring stiffness of the pipe, so as to enhance the pipeline load on soil resistance, in this performance, HDPE double wall corrugated pipe compared with other pipe has obvious advantages.Low construction costUnder the condition of equal load, the HDPE double wall corrugated tube needs only thinner tube wall to meet the requirement. Therefore, compared with the solid wall pipe with the same material specification, the material of the utility model can save about half of the raw material, so the cost of the HDPE double wall corrugated pipe is also low. This is another outstanding feature of this pipe.
Double wall corrugated pipe is a new type of light pipe with high density polyethylene as raw material, has the characteristics of light weight, high pressure resistance, good toughness, fast construction, long service life, the design of pipe wall structure excellent, compared with other structural materials, greatly reduce the cost of. And because of its convenient and reliable connection, it has been widely used at home and abroad. Mass replacement of concrete and cast iron pipes.
