flange¦s grade
flange¦s grade
(OP)
Hi, I am doing a Rerating of a pressure vessel; my problem is that I don’t know the grade of a flange (Class 600).
Does anyone know how can I do to obtain this information (consider that I haven’t got documentation of this flange), perhaps some geometric characteristic of the flange?
Thank you and sorry about my English.

As stated above a 16.5 flange should have the Class, material, heat # , and manufacturer stamped of the periphery.
RE: flange¦s grade
Are you uprating the vessel? Will changing flange materials get you there? You may not necessarily need to match flange and nozzle materials.
If you do have a B16.5 flange, this should be marked on it as well.
If you are uprating, you will need to confirm the entire design, not just the flanges.

You might find anything in a customer spec however.
