telltale hole / vent hole/weep hole
(OP)
As per ASME B 31.3, and ASME VIII, in RF PAD or PAD plate make hole for Pneumatic test and vent out the gas entrapped.
That hole should closed or remain open?
If it is inside vessels?
If it is out side of the vessels?

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

Only 2" nozzles does not required RF pad unless the designer has other judgment.

1) To allow hot air/gases to escape while welding the pad to the shell, especially the last part of the weld
2) to show if there is any leak in the underlying metal. RF pads are there to reinforce, not become pressure containing elements.
I've only seen them on the outside of vessels mainly due to ease of manufacture I would suppose.
