Product Feature

1, reduce the drainage noise.

Due to the unique design of the product, the water flow discharged from the horizontal pipe into the vertical pipe enters along the tangential direction to avoid the collision between the inlet water flow and the vertical pipe water flow, so as to ensure the spiral drop of the vertical pipe water flow and form a relatively dense rotating water flow, greatly reducing the noise generated in the drainage process.

2. Improve the flow status in the drainage riser and slow down the pressure fluctuation in the riser.

As the inner wall of the spiral pipe has regular spiral lines, the water flow in the drainage riser is obviously attached to the wall flow, which reduces the flow velocity and the drag coefficient of the water tongue. It can keep the central gas core in the riser connected up and down, keep the pressure fluctuation in the riser stable, and avoid negative pressure suction failure.

3. Increase the water and ventilation capacity of drainage riser.

Under the guidance of the screw protruder on the inner wall of the riser, the water flow falls spirally along the wall, forming a clear air column in the center of the drainage riser, improving the ventilation capacity, reducing the pressure in the pipe, increasing the drainage capacity, preventing the damage of the floor drain water seal, and improving the safety coefficient of the pipeline.

4, spiral muffler pipe strong ventilation ability, do not need to set up a special ventilation pipe.

Reduce project cost, raised dimensional utilization rate.

5. The triangular rib in the spiral pipe can strengthen the pipe wall and improve the impact resistance of the pipe.
