Dear Respected Members,

For a vessel designed as per section VIII Div-01, How does software such as PVElite determine vessel MAWP at the location of nozzle opening?

Did they use the formula mentioned in ASME section VIII Div-02 paragraph 4.5.5? or as per Appendix 1-10 in ASME section VIII-01?

Hello Moderators / Members,

Any comments Please?

The MAWP shall be determined from calculations based on the specified nominal component thickness(but reduced corrosion allowance), nozzle reinforcement or nozzle neck thickness shall not limit MAWP

Dear Holizhang,

Thanks for your reply.

As mentioned in your reply, if Nozzle reinforcement is governing MAWP of the vessel, how does PVElite compute it?

Dear All/Moderators,

Below mentioned is a statement from Result file of an pvelite model.

" Maximum Allowable Pressure for this Nozzle at this Location:
Converged Max. Allow. Pressure in Operating case 10.526 bars "

My question is how pvelite determines this value?

Does it uses any of the following clauses mentioned earlier =

"Did they use the formula mentioned in ASME section VIII Div-02 paragraph 4.5.5? or as per Appendix 1-10 in ASME section VIII-01?"

In this case This MAWP is determining vessel MAWP.

Kindly help.
