The specifications and sizes of PVC water supply pipes

The specifications and sizes of PVC water supply pipes are Φ20, Φ25, Φ32, Φ40, Φ50, Φ63, Φ75, Φ90, Φ110, Φ125, Φ140, Φ160, Φ180, Φ200, Φ225, Φ250, Φ280, Φ315, Φ355, Φ400, Φ450, Φ500 , Φ630, Φ720, Φ800, etc. The pressure shown in the PVC water supply pipe is expressed as the nominal pressure, expressed in Mpa. The nominal pressure is specified as 5 kinds of 0.63Mpa, 0.8Mpa, 1.0Mpa, 1.25Mpa and 1.6Mpa. The minimum diameter of pipes in each pressure zone is specified as follows: the minimum diameter of 0.63Mpa pipe is 63mm, the minimum diameter of 0.8Mpa pipe is 50mm, the minimum diameter of 1.0Mpa pipe is 40mm, the minimum diameter of 1.25Mpa pipe is 32mm, and the minimum diameter of 1.6Mpa pipe is 32mm. The minimum diameter of the pipe is 20mm and 25mm. The length of the pipe is generally 4m, 6m, 8m, which can also be negotiated by both the supplier and the buyer.
