Definition of repair 1

[Axel71]

Dear all, do you know where I can find the definition of "repair work" according to ASME code?

On a vessel (after PWHT) due to a fabrication mistake I have to remove up to 3 mm of material from the raised face of a 10" flange, is this considered a repair work according the ASME code?

after the machining work do you suggest to repeat the UT of the flange?

PS vessel is not U stamped

Thanks in advance and best regards

There is no formal definition of repair work type in ASME B&PV Code. You have either base material or weld defects along with misalignment or tolerance problems which are dealt with by welding or other forms of re-work.

The above are called conformances and should be dealt with according to the Certificate Holder's QA program.

after the machining work do you suggest to repeat the UT of the flange?

No. I would suggest a surface LPT of the machined surface.
