Suggestions on promoting new energy-saving and environmental protection water supply pipes in the new countryside to promote energy conservation and emission reduction and the development of circular economy. "The use of cold galvanized steel pipes and various composite cast iron water supply pipes is prohibited, and the use of hot galvanized pipes is restricted. It is imperative to promote the use of various new PE steel mesh skeleton plastic composite pipes and plastic composite pipes and other green pipes.
The steel wire reinforced mesh is added to the steel wire reinforced composite pipe, which not only greatly improves the pressure resistance compared with PE solid wall pipe, but also retains the excellent corrosion resistance and scale free characteristics of PE solid wall pipe. Its reinforcement is covered in continuous thermoplastic, which ensures the isolation of steel wire from the outside world, making the service life of steel wire longer and ensuring long-term pressure resistance. The steel wire mesh is wound to ensure a low linear expansion coefficient and a certain degree of flexibility in the axial direction, with strong environmental adaptability. Therefore, the steel mesh skeleton composite pipe is widely used in the field of water supply and gas supply.
Hainiu PE steel wire mesh skeleton plastic composite pipe is an upgraded product of traditional galvanized pipe. It is sanitary, non-toxic, non fouling, corrosion resistant, and has the advantages of small transmission resistance, light weight, easy installation, smooth and wear-resistant inner wall, long service life, and obvious energy-saving effect in long-term operation. It will not produce rapid stress that plastic pipe cannot overcome. PE steel wire mesh skeleton pipe has the strength, rigidity and impact resistance higher than ordinary pure plastic pipe, similar to the low linear expansion coefficient and creep resistance of steel pipe.
