Development of HDPE Water Supply Pipe

In the water supply and drainage pipeline system, plastic pipes have gradually replaced traditional pipes such as cast iron pipes and galvanized steel pipes and become the mainstream pipes. Compared with traditional pipes, plastic pipes have significant advantages such as light weight, corrosion resistance, low water flow resistance, energy saving, simple and rapid installation, and low cost, and are favored by the pipeline engineering community. At the same time, with the rapid development of the petrochemical industry and the continuous progress of plastic manufacturing technology, the output of plastic pipes has increased rapidly, and the types of products have become more diversified.

HDPE pipes are the second most consumed plastic pipes in the world after PVC-U drainage pipes. Medium or high-density polyethylene pipes of PE80 and PE100 grades should be used for gas transmission; medium or high-density polyethylene pipes of PE80 and PE100 grades are usually used for water supply pipes, and PE63 has been gradually eliminated. In terms of water delivery, the fastest growing is PE100 pipeline system, which is expected to grow by more than 10% in the next five years.

In Europe, HDPE pipes have been developed and applied more rapidly, and HDPE pipes have gradually replaced the status of PVC-U pipes and become the main consumption pipes. At the same time, HDPE pipes are gradually being used outside Europe.
