Nozzle Design on Flat-Sided Vessels
Nozzle Design on Flat-Sided Vessels
(OP)
I'm looking for a method to determine the allowable external forces & moments for nozzles on flat-sided vessels analogous to the methos for cylindrical vessels in the Pressure Vessel Handbook (Megyesy) [13th Ed., pp 153-158].
I considered using the Megyesy cylinder method, driving the vessel diameter to infinity to simulate the flatness, but I thought that there might be a simpler, and more reliable approach.

No, there is no closed form plug-in the number formula to do what you want to do and that's why FEA is really the only choice for this case.
If you have a flat sided vessel, then I highly doubt you have a pressure vessel. More like you have a bin, which is an atmospheric tank. If so, then you can just put some reinformcent gussets on the nozzle to stiffen up the joint if you really have to since this is no longer a Code equipment. I had done that a few times on rectangular bins which were used a lot in mining and copper refining and it works fine.

This is a internally reinforced & externally stiffened horizontally oriented process equipment with a decidedly net exteral pressure.
Thanks for the insight, though. Any more thoughts?
