Does ASME VIII require using ASME bolts on a bolted vessel
Does ASME VIII require using ASME bolts on a bolted vessel
(OP)
I have a 2 piece casted aluminum vessel that is bolted together at a center flange. This vessel has been given a u-stamp for years with no mention of the bolts. Inspectors at 2 different plant locations gave u stamp with no questions of bolts. Recently a new inspector is requiring specific ASME certified bolts to give u stamp. Can someone tell me where this is specified in VIII? Just when I think I have it figured out I read something else that makes me doubt....
Thanks!
Thanks!

So it doesn't say you have to use ASME bolts. It just gives requirements for bolting, so it's easier to show you meet the requirements by using ASME stamped bolts.

Far easier, as you do not have to establish the allowables for non-listed material. See UG-4, UG-10.
