I have a question regarding the design of pressure vessels, which is:
what is the 'maximum allowable working pressure'? i know the definition and all but i am struggling to understand whether the design pressure is based on the operating pressure or the MAWP?
For example, let the given operating pressure is 100 psi
so do we give a safety factor (of 30 psi or 10 percent) over this figure or that of the MAWP?
secondly, should the MAWP be greater or smaller than the design pressure?
