PVC-U Double-walled 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 decibels than the standard solid wall tube.
Good fire performance: the particle material has good fire performance, can meet the fire requirements of different fields.
Reliable and durable: pvc pipe and fittings with excellent durability, can withstand harsh environmental conditions and long-term use, with a long service life.
Good aging resistance and chemical corrosion resistance: the polyethylene pvc water pipe containing carbon black, can be stored in the open air, and will not be damaged by ultraviolet radiation. At the same time, it can withstand the corrosion of a variety of media, and the substances existing in the soil will not degrade the pipeline.
Good low-temperature impact resistance: pvc pipe fitting can be used safely within the temperature range of-60-60℃, and no pipe brittle crack will occur during winter construction.

Application
Building sound insulation:Widely used in building drainage systems such as residential homes and outdoor mobile home. in cinemas, recording studios and other places, the use of hollow wall muffler can effectively isolate the interference of external noise, to ensure the good indoor sound quality.
Traffic noise reduction: hollow wall pvc pipes are set on both sides of traffic roads such as expressways and urban expressways, which can absorb the noise generated by vehicles and reduce the impact of noise on the surrounding residents.
Mechanical vibration reduction: when the vibration and noise of mechanical equipment is large, the use of hollow wall muffler can effectively absorb the energy of vibration, reduce the propagation of vibration and noise, and ensure the stable operation of the equipment.
