Maximum Working Pressure And Design Pressure Of Flange

Publish Time: Author: Site Editor Visit: 45

When selecting Stainless Steel Flange, does the maximum non-impact working pressure of the flange pressure level correspond to the design pressure and design temperature or the operating pressure and temperature? For example, the operating pressure is 8.8Mpa, the operating temperature is 88℃, the design pressure is 9.5Mpa, the design temperature is 100℃, and the flange material is 16Mn. Should the flange pressure level be 600LB or 900LB? Three-ring flange: The maximum non-impact pressure when selecting the flange cannot exceed the maximum non-impact pressure of the flange selected at the flange design temperature. According to the manual, when 16Mn is at 100 degrees, the maximum non-impact pressure of the 600lb flange is only 9.02MPa, and the low-pressure design pressure is 9.5MPa, so a 900lb flange needs to be selected. The maximum non-impact pressure of the 900lb flange at 100 degrees is 13.53MPa, which can fully meet the design conditions, so the 900lb flange can be used with confidence.
