Nozzle design

[jwsmith88]

I have a request for a nozzle design that is located on the shell. It is oblong leaving the shell then has a transition (obround to circular) then a flange. Where do I look for the calculations to design this to ASME Section VIII Division 1? Thank you in advance for your help!

Ug-37 for reinforcement, UG-40 for limits thereof. If the flange is a custom design, then per Apx. 2.

No specific rules for required thickness of the nozzle neck at the obround, it will be a U-2(g) calculation. Often avoided for this reason.

Regards,

Mike

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

Thank you SnTMan.

Might add, you will likely need to check reinforcement in two (or more) directions, depends on the orientation of your obround. Good luck with it.
