PVC-U Hollow Spiral Silencing Drainage Pipe

   Hollow spiral silencing pvc pipe is mainly made of polyvinyl chloride resin as the main raw material, with necessary additives, kneading and extrusion materials added. The product has changed the traditional disordered drainage method of self gravity, and achieved an orderly water vapor separation by rotating the inlet spiral diversion. It forces the water flow along the pipe wall in the form of a water film, reduces the water flow velocity, lowers the water tongue resistance coefficient, and reduces the noise of the water flow affecting the pvc water pipe. The experimental results show that the noise power of PVC-U Hollow Spiral Silencing Pipe is only 30% -50% of that of ordinary PVC-U drainage pipe. Advantage Efficient noise reduction: PVC hollow wall pipe internal filled with sound absorption material, can absorb and eliminate noise and vibration energy, so as to achieve efficient noise reduction effect. According to the data, it can reduce the noise of 8-10…
