A Boiler Maximum Of 175 Kg Cm2


ASME SEC 1 PSVs set point - Safety Relief Valve

At 40 Kg/cm2 the set pressure tolerance is +/- 10 PSI (+/- 0.70 Kg/cm2) No temperature correction is applicable since the SV would normally have been set on steam. Above all, the set pressure should never be greater than the protected vessels maximum allowable allowable pressure MAWP.
