Speaking from possibly imprecise memory here:
TEMA Type W, packed floating head exchangers use a similar flange design at the floating tubesheet because the clearance between the packing flange and floating tubesheet is necessarily small. These units are of course moderate pressure and...
Well, I don't believe you can fairly call this a "reverse flange". It is more a variation on a Sketch 2-4 intergral flange to my eye.
Design of a similar desigh was discussed in this post...
If you can find it: Groups > List All Groups, scroll down.
I have it as "Watched" so didn't have to search for it (till now)
BTW, I don't get the joke either :)
No direct equivalent. This is a good opportunity for you to study B16.5 and gain the familiarity to answer your own question. Maybe work with a mentor.
Best of luck.
Well, first the B16.5 standard contains temperature-pressure rating tables for the various materials. Select the lowest class that meets your design conditions.
Second, confirm with the client. They may have a preference.

Well, I'll take a swing at this. Keep in mind I am not familiar with the latest.
I doubt TEMA has anything to say about this weld detail. I think it would be acceptable under Sec VIII, Div 1 subject to UW-13 rules, Fig UW-13.2
It is more common to introduce a short cylinder between the TS and...
