In the life, the pipes are used for transporting all kinds of liquid and gas. Both the indoor noise and the outdoor noise radiated by the pipe have greater influence on people’s life and work and damage people’s hearing. The piping noises are mainly from the fluid machine noises and are related to the fluid pressure, the fluid speed and the power source for transmitting the fluid, and the intensity of the pipeline radiated noise is related to the piping structure, the material rigidity and density and the piping wall thickness.
The noise generated by the drainage pipeline generating the maximum noise reaches above 70 dB, and the noise from the industrial piping even reaches above 100 dB, so the sound insulation treatment of the pipes is of great urgency.
If the piping is coated with ISOFELT_METAL (F10/F15), the piping noise radiation will be effectively reduced. The ordinary household drainage pipeline can be directly coated with OFF series metal sound insulation felt to meet the sound insulation requirement; before the use of OFF series metal sound insulation felt, the piping can be firstly clad with the superfine glass wool and the mineral wool for the industrial noise control, and finally the galvanized sheet is used as the shell protection faceplate, so that the high frequency and low frequency noise absorption can be increased to make its comprehensive sound insulation effect better.
