break out flange, back up flange was created by moradev
hello,
please can you explain to me what is the difference between a back up flange and break out flange? what is the purpose of using each one? is it related to the pipes insulation?
best regards

Back up Flange:
Also called Backing Flange, Lap Joint Flange, Van Stone Flange.
These are used in conjunction with "Stub Ends".
The Flange is slipped over the pipe, prior to the stub end being welded on.
The Stub-End forms the seal against the nozzle / Valve / flange etc that it is meeting. The backing flange is free to rotate until such time as it is bolted up.

Break out flanges are a set of flanges in a line, normally used if you foresee a reason to take out that piping section in the future, for maintenance, future expansion etc.
Your last question "is it related to the pipes insulation?": Back-Up flanges are not normally associated with, nor required for insulation.
