Snubber below silencer in open discharge PSV - is it right ?
In open discharge psv, after PSV pops up fully, force time history in the last open leg is steady which can not be withstood by a hydraulic snubber.
Moreover, at PSV inlet and outlet sections are small enough to withstand any bending moment arising out of yielding of snubber in steady load.
ASME B31.1 App-II 5.7.2 has shown a note of caution in repeated, not-so-transient load appearing in open PSV discharge.
I do not think snubber a right choice in open discharge PSV outlet below silencer; what our forum members think ?
