Pipe material

Technical Field

The invention relates to the field of building drainage pipes, in particular to a pipe.

Background

The plastic pipe is a common pipe for building drainage, but because the inner wall of the plastic pipe is smooth and has small frictional resistance, when the plastic pipe is used for a building drainage vertical pipe, the water flow speed is high, and when the flow is slightly large, water plug flow is easily formed (when the building drainage vertical pipe is used for gravity drainage, when the flow is overlarge, the thickness of a water film attached to the pipe wall is overlarge or the water flow is influenced by a structure, a central water cluster is formed by the water flow and falls in the pipe to form cluster plug-shaped water flow falling in the pipe). The pressure fluctuation is severe, the water flow noise is large, the sleep life of people is seriously influenced by the large water flow noise, and the phenomenon of odor return in a toilet is easily caused by the damage of a water seal to influence the improvement of the life quality. Chinese patent: CN201510072747.2 has proposed a building drainage plastics riser of taking spiral single vane, can solve the problem that the drain pipe is undulant violent, rivers noise is big when the flow is great to a certain extent, but the effect of solving the problem is not ideal enough, can't satisfy the demand that people pursue higher life comfort level.
