Thanks for all kind explanations and aswers.
Indeed what I mean is that according to some engineering procedures, e.g. Lummus criteria, when I calculate a vessel diameter I should approximate it do the next 6 inch. For instance, if I calculate 27,3 in I shoud use 30 in. I do not know why Lummus...
Regarding pressure vessels standard diameters, are vessels commonly fabricated with standard increments? If so, which is this increment?
Thanks in advance.
I have an existing vessel of A283GrC and I intend to use it for Propane at ambiente temperature (min 14 C). In case of depressurizing to atmosphere, temperature can be as low as -42 C due to evaporative effect. The minimum temperature reported by ASME for this material is -20 F(-29 C). Can I use...
