Hi
I have an interesting situation where the line between pressure vessel and pressure piping has been blurred. I would like to know if anybody is aware of a rule when to treat a component as a pressure vessel / boiler component / piping. We have a fired heater where some parties want the headers to be treated as pressure vessels and some want them to be treated as piping. The main issues are legal requirements (ie. pressure testing, documentation, etc), welding, design code (ASME Div 1 / B31.1 / API) and NDT.
Regards
