Urgent - out of levelness for shell flange
(OP)
what is the accepted out of levelness for shell body flange for re-boiler heat exchanger.
I found nothing in ASME VIII,API 660 and TEMA ,fortunately ; i found something relevant in Megasy PV handbook which is
The accepted out of levelness for nozzles flange is 0.5o.attached
But I am not confident that it can be applied on the body flange which may add extra stresses on the tube-to-tubesheet joint.
urgency wise could you advise ?

The criteria likely will be, will it pass hydro, will it seal in service. Don't think I'd be too concerned about the tube-tubesheet joint.

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

This has no easy answer, because it depends on the situation.
Are your concerns contractual or technical?
