Can any body shed some light on the existence of a standard or otherwise that governs the use of washers on studbolts? ie. When can you get away with not using them? Can apply to any application but specifically offshore oil and gas. Thanks!
Does ASME B16.5 allow for exceeding recommened pressure - temperature ratings, for a short, one-off period of time. ie. during pipeline hydrotesting.
I dont have a copy of the code handy, but if it does in fact address the above issue and someone could email the relavant pages, it would really...
ASME B16.5 spells out pressure - temperature ratings for carbon steel A105 flanges.
My question is: What kind of FOS has been incorporated, and can these ratings be exceeded for a brief duration, ie. during pipeline hydrotesting.
