Dear Makrand,
Thanks for your reply.
PVElite checks whether the nozzle is on Jacket or on Shell (nozzle penetrating through jacket) based on the internal projection given as input in the Nozzle Window), i.e. whether the nozzle internal projection is less than the jacket width or not. If the nozzle internal projection is equal to or more than the Jacket width, then the nozzle is considered on shell.
In my test.pvi file itself if you increase the internal projection of nozzle on Jacket to 150mm, it will consider that the nozzle is located on Shell (& not on Jacket) and then it will perform calculations based on the Design Pressure as Shell, i.e. 19 Kg/cm2.
I feel it will be better if the same programming is used for nozzle flange to check it’s temperature-pressure rating.
