We purchased 3/4" plate in advance, not intending to use it for primary steel members (all primary steel structure was supplied to us). Now we have to weld in some...

    ASME VIII Vessel flange angular tolerance

    Thanks for your help. As I say I don't have the customer's specs but we're looking at about 2.5 degrees out compared with the drawing. We are planning to do a direct replacement of an existing vessel, and reconnect the existing pipe, so the nozzle orientation is pretty critical, to minimise...

    Apologies, even cylindrical vessels have many angles. The vessel plan view shows the nozzle orientation with respect to 0degrees (e.g. Nozzle A at 90 degrees, Nozzle B at 125 degrees). I want to know if there is an allowable tolerance for this angular orientation in a plan view of a vessel. So...
