It's a common question I've seen in relation to over-pressure protection. It's both hypothetical and based on actual events, i.e. if a relief valve fails to lift within the code allowance, what are the ramifications of an over pressure event that exceeds the code allowable of 110% of MAWP (or...
Hi All,
Can someone point me to the standard that covers rules around how much the MAWP can be exceeded by before a pressure vessel has to be re-rated, or even de-rated? Is it just a pressure (I.E. anything over 1.3x MAWP), or is there other nuances like duration of over-pressure event etc.
