The b31 has an alternative rules in cases where its difficult to perform
hydro - after of course satisfying certain requirements. the alternative
test procedure aint easy either. Well youre either in conformance or youre
not. In some plants theyve set up a waiver policy meeting OSHA PSM
requirements in cases where the Code rules can not be applied. but one way
or the other critical equipment or process piping will have to undergo the
hydro to ensure that its still fit for continued service (no matter how many
times it has been NDE'd).
