- Commodity name: PVC-U spiral silencer pipe for building drainage
Hard PVC inner spiral pipe for building drainage made by Changhong Plastic Industry. It is mainly based on vinyl chloride resin monomer, with extruded inner wall of several convex triangular spiral ribs (with the pipe wall processing molding) of the round pipe, the triangular ribs have the function of guiding water flow along the inner wall of the pipe spiral fall, is mainly used in the building drainage riser pipe pipe. The appearance, specifications, dimensions and marks of the products shall comply with the relevant provisions of CECS94 2002 (Technical specifications for internal spiral pipe pipe engineering for building drainage).

The appearance, specifications, dimensions and marks of the products shall comply with the relevant provisions of CECS94 2002 (Technical specifications for internal spiral pipe pipe engineering for building drainage).
Due to the diversion effect of the spiral bar in the pipe, the water in the pipe rotates spirally along the inner wall of the pipe, forming a smooth air column in the center of the pipe, which increases the ventilation capacity by 5 to 6 times, and forms a stable and dense water flow in the inner wall of the pipe, which greatly improves the water flow capacity and significantly reduces the pressure fluctuation in the riser. The three or four passes are not connected with the drainage riser, and the sewage flowing from the cross branch pipe can be transferred
The flow is diverted into the riser from the tangential direction of the circumference, thus reducing the collision of water flow, creating conditions for reducing the noise of the drain pipe, while weakening the tongue of the branch pipe and avoiding the formation of water plugs. There is also a special structure under the tee to prevent the drainage of the reverse flow. This indoor drainage system has been used to prove its excellent displacement and ventilation effect.
At present, it is used in many buildings at home and abroad, among which, up to 140m, auxiliary ventilation pipes are cancelled. -
◆ Large displacement. For example, the diameter of 110mm spiral pipe water capacity of 6L/s, because the system omitted the vent system, not only save materials, save labor and other installation costs, while increasing the indoor use area.
◆ Because the spiral pipe reduces the noise by 5~7dB than the ordinary plastic pipe, it creates a good home environment.
◆ Due to the good decompression performance of the spiral pipe, it greatly improves the safety factor of the drainage pipe of high-rise buildings, and also reduces the possibility of the overflow of the toilet formed for various reasons.
◆ Because the pipeline system adopts flexible wire connection, it is not only easy to install and maintain, but also has beautiful appearance and good seismic effect.
◆ Building drainage hard polyvinyl chloride (PVC-U) inner spiral pipe is mainly used in the drainage riser in the building. -
