Problem:
Can a reinforcing pad be placed on both shell locations of a vertical vessel in AutoPIPE Vessel?
Solution:
The program will easily model a reinforcing pad at Location #1, but not at location #2. Furthermore, reviewing the warning messages after the analysis the following maybe displayed:
"337 NOZZLE xxx: elbow on head, the reinforcement on the external shell should be checked using another calculation."
Therefore, currently, only the opening for the location #1 (head) is checked by AutoPIPE Vessel, for the location #2 in the cylindrical shell there is no verification. The user will need to do a separate verification of this special/specific opening.
Furthermore, the opening can be checked in another model but take into account the two different pressures and temperatures applied on this opening: pressure/temperature in the nozzle and the pressure/temperature in the shell. This case is not described in the pressure design codes.
