The drain pipe is used for drainages, such as drainage, rainwater, and community drainage on real estate projects. The drain pipe itself has no pressure, can not withstand the pressure, and has no requirements for the health indicators. If you want to distinguish the quality of the pipe, it depends on its toughness and tensile properties. The water supply pipe is self-evident for use in the water supply. Of course, it is also used for the irrigation of farmland. The difference between it and the drainpipe is that it needs to withstand the pressure. If it is for the water supply project, it also needs health indicators. , non-toxic and non-polluting, and other indicators. Main difference: 1. Pressure: the pressure is different. 2. Pipe Diameter: the diameter of the drainpipe is large, generally DN50, the pipe diameter of the water supply pipe is small, generally DN15. Pipe specs: Commonly used PVC water supply pipe specifications are Φ20, Φ25, Φ32, Φ40, Φ50, Φ63, Φ75, Φ90, Φ110, Φ125...
