Using B16.5 Flange Bolting to Secure a Bracket
Using B16.5 Flange Bolting to Secure a Bracket
(OP)
Hello,
I would like to secure a bracket to a stud bolt on a B16.5 pipe flange. The bracket will be sandwiched between two hex nuts as shown in the attachment. I would like feedback on whether this approach is acceptable per ASME standard or code. I was unsuccessful finding anything in ASME B16.5 or ASME PCC-1 related to using a flange bolt in this manner.
Thanks in advance for your input.

Looking at your drawing I can't see it being a big issue or load on the flange but why is it not between the nut and flange? Saves another bolt and longer nut.

Ability to remove and/or adjust orientation of the bracket without unloading the gasket?

Look at pipe flange supports where lots of people use plate supports on bolt holes to support pipe and valves but they all go between the nut and the flange itself.

We will however allow support to be bolted to flange particularly on GRE etc and typically at valve locations.

LittleInch, the longer bolt and second nut provides the ability to adjust or remove the bracket without unloading the flange (just as jgKRI thought). I don't see this needing to happen but just in case. Thank for you for mentioning flange style pipe supports. I was unfamiliar with this product until now.
MickMc, in this case a second pipe will not be supported by this bracket. The item being secured is able to move with the flange as it moves.
moltenmetal, I was also interpreting the flange joint as ending at the top of the first nut.
