Product Feature:

1.Six streamlined spiral internal ribs enable water to swirl down against the inner wall of the pipe,greatly reducing the noise of the pipe system.

2.The outer wall of the pipe is a hollow and porous structure,in which the empty layer can further block the noise generated during drainage to enhance the sound elimination effect of the pipe.

3.Under the guidance of the spiral internal bar of the pipe,the water flow falls spirally along the wall of the pipe, and the unblocked air column is formed in the center of the drainage riser,which has a strong ventilation ability.No additional exhaust pipe is needed to reduce the project cost.

4.The spiral muffler pipe fitting with unique design makes the water flow into the riser along the tangential

direction to reduce the collision of water flow and thus reduce the noise.The pipe fitting can also play the role of expansion joint to compensate the change of pipe length caused by thermal expansion and cold contraction.

5.The hollow structure of the outer wall of the pipe can play a good insulation effect and prevent the condensation phenomenon on the outer wall of the pipe.

Product Application:

It is suitable for the indoor muffler drainage system of high class office,conference hall,hotel,guesthouse, apartment,villa and high grade residential area.
