PWHT Blind Flanges
PWHT Blind Flanges
(OP)
I haven't seen a thread that relates to this question.
I am PWHTing a vessel that has 2 manways and 1 4" vent with a blind flange. They are SA-105N. Do these blind flanges need to be PWHT'd ? Why/why not ?
Thank you

There is usually something welded to the blinds, anyway.
Maybe not required, but the furnace is hot anyway.
