I have a situation where I would like to consider using a standard F & D head in place of an ASME F & D head in a non-code vessel application. I have some internal and external loading that needs to be considered but I am struggling with how to use the formulae for a knuckle radius other than 6% (ASME F & D head), which appears to be required to use formula UG-32(e).
Can you guide me to the proper formula to use for calculating loads on a standard F & D head?
