I have a an ASME VIII Divison 1 vessel which is now finished, tested and sitting at site.
However one nozzle is of an incorrect size. We need to replace this nozzle with a larger one.
Welding will be done with an approved weld procedure at site.
Welds wll be 100% Dye Penetrant tested.
My question is - do we need to re do the ASME code hydrotest as we have cut into the vessel pressure envelope.
If I were just welding a an external pipe support clip to the vessel without cutting the shell / ends then I would not apply another hydro-test
Any comments / help will be most helpful
