Sec VIII App2 Flange Question

Sec VIII App2 Flange Question

Sec VIII App2 Flange Question

(OP)
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 other words, there is no rule against moving the weld joint further away from the hub as long as hub geometry remains 1:3, correct?

Thanks!

RE: Sec VIII App2 Flange Question

That dimension is not otherwise promoted by the rules in Appendix 2.

RE: Sec VIII App2 Flange Question

a) Not a standard detail, a single slope would be within Apx 2. b) Doesn't make sense to do it anyway, IMO. Why add unneeded length to the hub? It'll cost to do it.

Regards,

Mike

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

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 advantageous.

RE: Sec VIII App2 Flange Question

Well. I'd say make the hub as long as you need, but with a single slope or even a straight hub. I have found it more practical to bend my designs to fit the Code, rather than the other way around :)

Regards,

Mike

RE: Sec VIII App2 Flange Question

Slope is 1:3 max. So if you nedd a longer hub, you would adopt a smaller slope (straight to the weld) to reduce discontinuity stresses.
