Pressure Vessel Flange Calculation
Pressure Vessel Flange Calculation
(OP)
In the attached computer program (pg 22) there is a design calculation for the flange. Under bolting information, there is a value of 25 ksi for Material Stress Hot (Sb) and Material Stress Cold (Sa). What exactly are these values? Are they allowable stress?
