boiler's maximum allowable working pressure. Additional Safety or Safety-Relief Valves shall be set at less than 103% of the boiler's maximum allowable working pressure. For saturated steam lines, the highest valve's set pressure must be less than 110% the lowest valve's set pressure (unless the valve is a Safety-Relief Valve on a high-temperature water boiler).

The 248 PSI is the MAWP and will go to the nameplate and will be the base for calculation of test pressure for hydrostatic test pressure. As you can see, your maximum allowable working pressure always is greater than design pressure. In the worse case scenario that can be equal to design pressure but never will be less than that.

Feb 28, 2020 · Maximum allowable working pressure (MAWP) is an American Society of Mechanical Engineers (ASME) designation that establishes the rating for pressure-relief components on vessels. It measures the greatest amount of pressure that the weakest part of the vessel can handle at specific operating temperatures.

ASME Boiler Tube Thickness Calculator. C = minimum allowance for threading and structural stability (see PG-27.4.3) D = outside diameter of cylinder. E = efficiency (see PG-27.4.1) e = thickness factor for expanded tube ends (see PG-27.4.4) P = maximum allowable working pressure (see PG-21) R = inside radius of cylinder; for pipe, the inside radius is determined by the nominal outside radius minus the …
