PVC给水管的规格尺寸有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等。PVC给水管所示的压力均表示为公称压力，用Mpa表示。公称压力规定为0.63Mpa、0.8Mpa、1.0Mpa、1.25Mpa、1.6Mpa等5种。每个压力区的最小口径的管材规定为：0.63Mpa管材的最小口径为63mm，0.8Mpa管材的最小口径为50mm，1.0Mpa管材的最小口径为40mm，1.25Mpa管材的最小口径为32mm，1.6Mpa管材的最小口径为20mm和25mm。管材长度一般为4m、6m、8m，也可由供需双方协商而定。
The specifications and sizes of PVC water supply pipes are Φ 20, Φ 25, Φ 32, Φ 40, Φ 50, Φ 63, Φ 75, Φ 90, Φ 110, Φ 125, Φ 140, Φ 160, Φ 180, Φ 200, Φ 225, Φ 250, Φ 280, Φ 315, Φ 355, Φ 400, Φ 450, Φ 500, Φ 630, Φ 720, Φ 800, etc. The pressure indicated in PVC water supply pipe is expressed as nominal pressure, expressed in MPa. The nominal pressure is 0.63Mpa, 0.8MPa, 1.0MPa, 1.25mpa, 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 20mm and 25mm. The pipe length is generally 4m, 6m and 8m, which can also be determined by negotiation between the supplier and the demander.
