What is a polypropylene ultra-quiet drain pipe?

Polypropylene silent drain pipe adopts three-layer extrusion production process, and the raw materials are recyclable environmentally-friendly impact-resistant polypropylene resin and special sound-absorbing materials. After modification, it has good noise reduction and mute performance, chemical corrosion resistance and heat resistance. Its performance has reached the international advanced level, filling the domestic gap. PatentNo.: 01144193.32. Scope of application: mainly used for drainage and sewage discharge of office buildings, high-grade apartments, hospitals, sanatoriums, embassies, schools, AAA residential buildings and industrial buildings. Excellent noise reduction and quietness: by adding special materials, the density and microstructure of the pipeline can be adjusted, the audible sound waves can be absorbed, and the sound waves can be prevented from coming out. The noise reduction effect is better than that of cast iron pipes. Super chemical resistance: the acid resistance of the inner and outer layers of the pipe can reach PH2, the alkali resistance can reach PH 12, and the liquid with PH2-PH 12 can be discharged. Excellent high temperature resistance: the mute tube can withstand 95 degrees hot water for a long time. Good impact resistance: the hard outer layer not only protects the intermediate structure, but also ensures that the pipe has good impact resistance. Advanced flexible connection: easy to disassemble and assemble, which can reduce the installation cost. The water tightness and self-adjusting performance are good, and each pipe fitting can achieve the effect of expansion joint without using expansion joint. Environmental performance: Polypropylene is a green material, which can be recycled. Implement CJ/T273-2008 polypropylene silent drainage pipes and fittings.
