Full Vacuum Design Pressure Assumption
Full Vacuum Design Pressure Assumption
(OP)
I have a pressure vessel with design pressure 100 barg. Is it acceptable to assume that the vessel can withstand full vacuum also?
Thanks.
Thanks.

The problem with sloppy work is that the supply FAR EXCEEDS the demand
RE: Full Vacuum Design Pressure Assumption
You know what they say about the word ASSume...
That said, there is a good likelihood that the calculations will pass, provided the D/t ratio is not too high, nor the L/D ratio, and the temperature is not excessively high. You do understand that the failure mechanisms are very different between internal and external pressure, and hence a simple assessment is not possible?
RE: Full Vacuum Design Pressure Assumption
At 100 psig design pressure, if the vessel is steel, and the diameter is less than 36 inches.....then yeah...probably.
It is an easy and straightforward thing to perform a calculation and check this....
I suggest that you use either the PV handbook or the Bednar PV text

You'll most likely be okay, but calculations are required.
