Dear My Freinds,
I will be pleased if anybody answer my question.
Generally we avoid falling MAWP on nozzel instead of shell and flange.
Do we have to do it or is it optional?

Hello Naderi

I am not quite sure what your question is, but this what I think you mean: Is their a way of ensuring that the nozzle does not limit the MAWP of the vessel. If this is the case, there is a way in PVElite. If you click the 'Load Cases' tab (usually at the bottom of the screen), then go to 'Nozzle Design Pressure Options'. From the drop down box, choose '4 MAWP plus static head to nozzle', and the nozzle will not limit the MAWP of the vessel.

Dear Delaforce,
Thank you very much for your attention.
Please let me explain my question again.
In the output of Pvelite, the nozzle summary section, after sumerizing nozzle in a table, Pvelite mentions Min of M.A.W.P for Nozzle and Shell&Flange.
My question is:
Is it crutial that we avoid falling of Min of M.A.W.P on nozzle.
For instance, it is necessary that M.A.W.P of nozzel be greater than M.A.W.P of shell&Flange.
I will appreciate if you let me know your answer.
Best Regards,
Naderi
