See Table of loads and orientation drawing:
We are assuming that you are asking for values for the forces and moments which may be applied to each flanged nozzle.  We have come up with the values per the chart below (the excel spreadsheet of this chart is attached.).  See the attached PDF diagram for the orientation of the forces with respect to each nozzle.  Note that the forces and moments are applied to the shell where the nozzle meets the shell.  Your pressure vessel design program should do this for you.
