Plastics and traditional materials are different, and the pace of technological progress is faster. The continuous emergence of new technologies, new materials, and new processes make the advantages of plastic pipes over traditional materials more and more prominent. Compared with traditional metal pipes and cement pipes, plastic pipes have light weight, generally only 1 / 6-1 / 10 of metal pipes, and have better corrosion resistance, impact resistance and tensile strength. The cast iron pipe is much smoother, the friction coefficient is small, the fluid resistance is small, it can reduce the energy consumption of water transportation by more than 5%, and the comprehensive energy saving is good. The manufacturing energy consumption is reduced by 75%. .Polyethylene tube
Polyethylene pipes have developed rapidly in various countries in the world in the past 10 years. Developed countries have an absolute advantage in the application of polyethylene pipes in the field of water supply and gas. Polyethylene pipes are not only used in large quantities to replace traditional steel pipes, cast iron pipes, etc., but also replace PVC pipes. The reason lies in the technological innovation of polyethylene pipes in the past 10 years. On the one hand, the material has made significant progress. Through the improvement of the production process of polyethylene polymerization, the strength of the special material for polyethylene pipes has almost doubled.
On the other hand, there are new developments in application technology. For example, in recent years, the technology of laying polyethylene pipes without digging trenches and using directional drilling methods has fully utilized the advantages of polyethylene pipes, making traditional pipes suitable for this method. There is no competitiveness at all. There are still many new materials and technologies being researched, or have been researched and are being tested for trial. It is certain that the technological progress of plastic pipes in the next 10 years will promote the rapid development and expansion of plastic pipes.
