Thanks for the input TGS4 & SnTMan. My sketch was a simplified version of the actual flange...while there may be an increase in material or machining costs, the change will facilitate our welding process and move heat away from the flange sealing surface, which in this specific case is...
Hello,
Regarding integral type flange shown in Figure 2-4(6), Section VIII Appendix 2...
As long as g0, g1, and h (hub dimensions) result in a hub slope not exceeding 1:3, is there a limit to the distance the C/L weld is located below the end of the hub length (where h and g0 intersect)? In...
gr2vessels,
Thank you for the reply. Although, I am not finding where a studding outlet or tank-style pad flange is addressed in B16.5. If it were, I agree that Note (b) of Table 1A would clearly answer my question. This being a tank fitting (albeit one mating to a pipe fitting), the answer...
Hello,
I’m trying to find info in Section VIII regarding material selection for a pad flange/studding outlet that will weld into a tank head or shell wall. I’m specifically trying to determine if ID/OD plate (not plate rolled into a ring & welded) can be for this type of flange. This is a...
Does anyone know what prompted the addition to UHA-51 requiring impact testing for UNS S17400 materials in the 2013 Code?
Thanks (pardon the cross-post)

Hello,
I have two nozzle openings in a torispherical head. Both 3.94" ID, centers spaced 6.5" apart. If I consider these openings individually, there is adequate strength in the shell, nozzle & welds, that no additional reinforcement is required. I think I understand the rules of UG-42a...
Fig. UG-34(a) shows a shell thickness (ts) & a head thickness (t) transitioning with a taper. I'm assuming that the figure points this out to show when the shell thickness is thinner than the head thickness, there must be a tapered transition between the two. It's not, however, stating that...
