Pressure used for nozzle thickness and reinforcement calculation.

[Arsan16]

We have a vessel having internal coil with higher design pressure than that of vessel. For calculating the coil inlet and outlet nozzle thickness and reinforcement do we have to consider the design pressure of coil which is higher?

Yes, and it is relatively easy, however current available software doesn't handle this scenario, therefore you will need to do it by hand.

Hi DriveMeNuts .. Thanks for the response... I think we can run the calculation separately for these nozzles with a user defined MAWP value same as the coil design pressure..
