Allowable Loads and Moments in Head Nozzles
Allowable Loads and Moments in Head Nozzles
(OP)
We need the maximum loads in moments for a 36"-150# nozzle located at the top of a column. The WRC-107/297 is only for shell nozzles. The loads charts available for is up to 30". Please tell me how we do to get these values.

The 36" nozzle is quite a large size for a nozzle in top of the column, however, you probably don't get the piping loads for a 36" pipe size. Usually, the loads imposed on that nozzle are much lower and you should work with estimated operating loads instead of theoretical, design loads, or you should discuss with your piping designer to limit the loads, by clever piping lay-out. Usually, the FEA is not warranted for such simple nozzle load, but you are the final judge for the complexity of external loads and the feasibility of an expensive FEA.

BTW, what is the ratio of the d/D (nozzle dia / head dia)?
