Obround Internal Pressure Calculations for Pressure Vessel

[Tronic777]

Hello,

I am experimenting with designing an obround pressure vessel to ASME Section IV and couldn't find which section would specifically define calculations for such a shape. The calcs which I am finding are mostly for Obround openings and not the actual shape of the pressure vessel itself. Is anyone able to direct me to the right direction? (Section VIII Calcs may also help in designing this? I believe if it conforms to the higher requirements of Section VIII, it certainly will be 'over-engineered' for section IV).

See Sec VIII, Div 1, Apx 13.

The problem with sloppy work is that the supply FAR EXCEEDS the demand
