Dear all
While carrying out differential pressure design for a U bundle exchanger using PV Elite, the differential pressure (shell side more than tube side) is being applied.

During external pressure check for tubes,we understand that tubes are checked for the actual shell side pressure as external pressure rather than differential pressure in PV Elite

Can somebody clarify the same

Thanking You and With regards

I think differential pressure design option is only for tubesheet. You may check again.

you have to be careful in designing tubes for differential pressure only. If you have an accidental overpressure you can easily crush them.
