How would I go about calculating / estimating the wall thickness required for a pressure vessel?
I'm designing a vacuum vessel operating at 10 to 40 Torr (2 stage). The external pressure will be ambient (atmospheric).
Is there a design standard / equation for this based on the vessel geometry? (Cylindrical with hemispherical ends)
- Material of construction could be carbon steel / stainless steel therefore material data could be researched (max allowable stress etc)
- Operating presssure of 10 Torr, therefore design pressure would be in the region of 6-8 Torr I'd imagine
Presumably there's an API / ASME standard for this sort of thing, but my limited googling skills have once again faltered!
Any help would be greatly appreciated.
