PVC drainage pipes have been used more and more widely in various industries. The most important material of PVC drainage pipes is polyvinyl chloride. PVC has strong heat resistance and corrosion resistance, which is why PVC One reason for widespread use.
The indoor rainwater drainage system is more and more widely used for the purpose of making the facade of the building more beautiful. The indoor rainwater pipeline is generally designed according to the non-pressure flow, but because the rainwater flow is sometimes large and concentrated, the pipeline is simultaneously There are two states of gravity flow and pressure flow, so the indoor rainwater pipeline is required to have stronger pressure resistance than other drainage pipelines.
PVC drainage pipe is a substitute for traditional drainage pipe and has better physical and chemical properties. Its inner wall is smooth and has less frictional resistance than conventional drainage materials, so the horizontal pipe installation slope is small, which can improve the indoor height of the building. PVC drain pipe is lighter in weight, one-fifth of the cast iron pipe, easy to transport and operate; it is glued for easy installation and maintenance; the price is lower than the conventional drain pipe, which greatly reduces the construction cost; the corrosion resistance is strong, in the construction Sewage wastewater and rainwater pipeline systems are commonly used. In addition, the widespread use of PVC drainage pipes is conducive to saving steel, which is of great significance for alleviating the shortage of steel in China. Compared with cast iron pipes and steel pipes, PVC-U drainage pipes are subject to The disadvantage of low pressure and weak impact resistance. In addition, although the PVC-U drain pipe is a flame-retardant material, there is a possibility that the fire spreads upward along the drain riser for the indoor bright-seal pipe.
