We have a 30" B16.47 std blind flange as top cover of a vertical vessel. On this flange a 2" hole to be drilled centrally to fix a nozzle on it. Can we proceed with a standard flange without doing an Appendix -2 calculation.
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..
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?
