UPVC spiral pipe drainage system
1, drainage and low noise.
2, to prevent damage to seal leakage.
3, the drainage capacity, easy to plug.
4, the overall project cost than traditional cast iron pipe by 20% -30%, and the soft colors, to overcome the monotony of the cold gray cast iron pipe.

UPVC drainage system in ordinary spiral pipe drainage system is the same basic components, is different: First, by using the drain riser PVC material coil, pipe wall together with the inner walls forming process six prominent triangular spiral rib pipe flow along the tube wall spiral drop, the formation of more stable and dense film of water swirl, control center is a smooth column of air, water drop limit velocity have also been reduced, significantly reducing the riser pressure fluctuations, greatly improve the drainage capacity, and effectively enhance strength and stiffness of the pipe. Second, the ordinary pipe fittings and different, that is, horizontal branch pipe connected with the use of lateral water riser tee or four-way dedicated pipe to prevent lateral water flow and decrease the impact, beneficial water along the riser wall rotating drop.
