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
Any ideas?

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.

Many Thanks

Just find a copy of the following:
ASME Boiler & Pressure Vessel Code. It has the rules for construction of pressure vessels.

Probably you want a quick rough "estimate" (e.g. to estimate capital cost), as your post may indicate (calculating / estimating). In this case look at the previous thread http://www.cheresou...ss-calculation , mainly post No 4. Referred book of Coulson and Richardson is useful.
