Flat head with internal hemispherical radius

[ElCidCampeador]

Hello,
I'm designing a pressure vessel acc. to ASME VIII Div.1, Mat. S.Steel.
This vessel has a shell from seamless pipe and welded at both ends 2 forged caps. These caps are externally flat, but inside they are emispherical.
I checked these heads acc. to UG-32 (Hemispherical heads formula).
Should I check also according to UG-34 flat heads formulas and fig. UG-34, e.g. detail b-2?
I suppose that UG-34 refers to flat head with constant thickness, but in my case thickness has a minimum (center) and a maximum (periphery) growing acc. to radius of the inside sphere...How should I interpret it?

Thank you

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Yes, I'm an idiot...

By the way, I've been working too much. Thank you (and sorry)
