Section VIII Div.1 MAWP
Section VIII Div.1 MAWP
(OP)
It has been told by my Authorized Inspector that if you blow a hole into a 16.5 flange (for the purposes of attaching a nozzle) that it is no longer considered 16.5. At this point, flat head calculations of UG-34 and UG-39 must be used.
How do I calculate the MAWP for this part since it is no longer 16.5? I cannot find a formula like shown in UG-27 or UG-32 for example. THANKS

The problem with sloppy work is that the supply FAR EXCEEDS the demand

You didn't flip enough pages. Keep reading until you get to UG-34, and pay particular attention to Figure UG-34(j). Then for opening reinforcement, be sure to skip UG-37 and proceed directly to UG-39.
But before you go to all that effort, be sure to look at B16.5 Table 6 and make sure that your (centered) opening in the blind does not exceed that which is permitted. If you don't exceed the permitted opening size, then it is still compliant with B16.5.
