Is weep hole in the repad of the nozzle an ASME requirement?

hi Mecheng29,

I was just about to tell you to post a new thread since you posted this topic in mine hehehe... and the answer to your question is yes my friend....please refer to UG-37(g) in ASME sec VIII div 1 and you'll see that at least one weep or tell tale hotel is required for pads. hope this helps.

This weep hole is normally filled with sufficient grease.

Nozz repads yes; lug, etc repads no.

The reason for the weephole in the nozz repad is so that the welds on this repad can be 'soap-bubble' tested. This repad is tied into the vessel shell, with a weld to the nozz, and that weld extenss along the nozz to the process side of the vessel.

Lifting-lug repads do not have welds that extend into the vessel. Only a mechanical attachment, thus no mandatory weep-hole and 'soap-bubble' test. Still a good idea, though.
