PVC-U solid wall spiral silencer pipe
Product features of Bailian Plastics PVC-U solid wall spiral silencer: 1. Reduce drainage noise
Product details
BailianPlastic industry PVC-USolid wall spiral silencer
Product Features：
1Reduce drainage noise. Due to the unique design of the product, the water flow from the horizontal pipe into the vertical pipe flows in a tangential direction, avoiding collision between the incoming water flow and the vertical pipe water flow2Ensure that the water flow in the riser spirals downwards, forming a relatively dense rotating water flow, greatly reducing the noise generated during the drainage process.
3Improve the water flow state inside the drainage riser and slow down the pressure fluctuations inside the riser. Due to the regular spiral lines on the inner wall of the spiral tube, the water flow in the drainage riser exhibits obvious wall attached flow, reducing the water flow velocity and the water tongue resistance coefficient. This can maintain the upward and downward connection of the central air core in the riser, smooth pressure fluctuations inside the riser, and prevent negative pressure suction damage.
4Increase the water and ventilation capacity of the drainage riser. Under the guiding effect of the spiral convex device on the inner wall of the riser, the water flows down in a spiral shape along the pipe wall, forming a smooth air column in the center of the drainage riser, improving the ventilation capacity, reducing the pressure inside the pipe, increasing the drainage capacity, preventing the damage of the ground leakage seal, and improving the safety factor of pipeline use.
5Spiral silencing pipes have strong ventilation capabilities and do not require separate ventilation pipelines. Reducing project costs and improving space utilization.The triangular ribs inside the spiral tube have a strengthening effect on the pipe wall, which can improve the impact resistance of the pipeline

）Bailian Plastic industry
Solid wall spiral silencing pipe
detailed descriptionBailian Plastic Industry's solid wall spiral silencer is made of rigid polyvinyl chloride（PVC-U
）As the main raw material, essential additives are added, and advanced production equipment and process technology are used. The extruded inner wall of the tube has several triangular spiral ribs and a circular tube with reduced drainage noise. The triangular spiral ribs protruding from the inner wall of the pipe are used to guide the water flow to spiral down along the inner wall of the pipe, forming a smooth air column at the center of the pipe, significantly reducing pressure fluctuations inside the riser, improving drainage capacity, and reducing noise in the pipeline system.
