I suppose that this is a Fire Tube  Boiler still under manufacturing process.
I assume that the pin holes have been detected on the weld attaching the furnace to the tubesheet.
I assume also that the pin-holes have been detected by means of PT.
Well, Section I does not formally require an inspection by PT at this area. This is not a joint like those addressed in PG-93.2.

If above assumptions are true, you have performed an inspection beyond the Code requirements.
However, since you have done this, you have to look in A-260 for the acceptance criteria (unless they are through pin-holes which will cause leakage)  and then you have to act as required by PG-90.1.10
