Hello all forum member
Since last many times ,we are facing some issue related to nozzle qualification in PVElite 2014
Actually I am Piping stress engineer and we have checked our nozzle in Caesar II Inbuilt WRC-107.
Looks like nozzle is well qualified in WRC-107 but with same load PVElite Calculation shows Failure (Refer below snap of PVElite).
When I saw the results of PVElite I surprised that why mechanical needs to perform this calculation as per B31.3
Same thing we are checking in Caesar II software
I searched this point on google found that PVElite has option to ignore this check
I am not able to find out that option from PVElite 2014/2016.
Please guide me on this further for how to switch off this check from above mentioned PVElite version.
Let me know if you want anything else.

Procedure

1)During initial stage of project we have submitted Nozzle loads to our Mechanical Department for getting quate from Vendor based on standered formula
2) Than we will model exact Piping in our Caesar and calculate actual load coming on the nozzle,Perform WRC107 check (Caesar inbuilt).

3)Than we will submit that loads to vendor through mechanical dept for their approval.

want to know your views

Thanks in advance

Hello Stressguy stress 1698),

Actually, those are the stresses in the nozzle, not in the shell. However, as I understand it, CAESAR II should be able to do a more sophisticated calculation if you have a branch and header situation. I am a vessel guy, not a piping guy, but I think that if the piping system passes in CAESAR II, you don't have anything to worry about.

Thanks for quick reply

but can you please guide me how to ignore that check from PVElite 2016

i know that PVElite 2017 has option to avoid this checking.

thanks

Hello Stressguy stress 1698),

Actually, if you have the 2017 version of PV Elite, you can do just that. Just go to Tools->Configuration, and you will find a check box where it is possible to switch it off. Look in the Nozzle group of boxes.
