Acc to ASME I, if the thickness of the shell is greater than one-half of the inside radius then the calculation should be carried out acc to PG-27.2.3 which says:
The maximum allowable working pressure for parts of boilers of cylindrical cross section, designed for temperatures up to that of saturated steam at critical pressure [705.4°F (374,1°C)], shall be determined by the formulas in A-125.
Does this mean that the formulas in A-125 are only valid if the design temp. is less than 374,1°C?
My design pressure is 107bar and design temp is 535°C, so is it even possible to use ASME I for the design of my "thick shell"?
Thanks
