Pressure grade

we have S5, S4, S3.2, S2.5 series of four grades, usually the hot water pipe select S3.2, S2.5 two series, selection of cold-water pipe S5, S4, S3.2 c series. According to different requirements of the safety factor, the selection of pipe systerm1.25mpa or 1.5mpa, the relationship between S and nominal pressure PN in the table below,
