Application advantages of plastic pipe

Plastics are different from traditional materials, and the pace of technological progress is faster. The continuous emergence of new technologies, new materials and new processes makes the advantages of plastic pipes more and more prominent compared with traditional materials. Compared with traditional metal pipes and cement pipes, plastic pipes are light, only1/6-110 of metal pipes, and have good corrosion resistance, impact resistance and tensile strength. The inner surface of plastic pipe is much smoother than that of cast iron pipe, with small friction coefficient and small fluid resistance, which can reduce the energy consumption of water delivery by more than 5%, comprehensive energy saving and manufacturing energy consumption. Polyethylene pipes have developed rapidly in the world, and the application of polyethylene pipes in water supply and gas fields in developed countries has taken an absolute advantage. Polyethylene pipes are widely used not only to replace traditional steel pipes and cast iron pipes, but also to replace PVC pipes. The reason lies in the technological innovation of polyethylene pipes. On the one hand, material has made great progress. Through the improvement of polyethylene polymerization production process, the strength of polyethylene pipe special material is almost increased by 1 time. On the other hand, there are new developments in application technology, such as laying polyethylene pipelines by directional drilling without trenching, which gives full play to the advantages of polyethylene pipelines and makes traditional pipelines uncompetitive in occasions suitable for this method. There are still many new materials and technologies under study, or they have been developed and are being tested. It is certain that the technological progress of plastic pipes in the next 10 year will promote the rapid development and wider application of plastic pipes.
