acceptable flange usage
acceptable flange usage
(OP)
Would like some input. We have an engineer who has, due to a machining error on a threaded hole for some electrical feedthru on a 1500# RF flange, decided to turn the flange around and us the normally atmosphere exposed side to mate with the companion RF flange. His assumption is that it will work like a FF flange. This is on a code certified pressure vessel. Expected temp range is 200 C at 600 psi mineral oil.
Comments on this practice would be appreciated.

RE: acceptable flange usage
Normally you can cleanup the backside and relieve the flange to configure it as a raised faced flange and use it as a normal flange. With your conditions there should be problem.
You should document, evaluate using the flange in the reverse with the new dimensions, after reworking of the flange.
