Optional type of flange 8a (ASME code)

[arondelo]

If I design a flange like in sketch 2-4 8a as integral, what are the "h" and "g1" values I should use? See the drawing.

I'm not sure if I am supposed to calculate as a normal weld neck flange, or consider only the dimensions of the weld fillet.

Thanks.

Is this a silly question?

As per ASME code, that flange can be calculated as integral or loose, but, in my opinion, the code is not 100% clear about what are the h and g1 dimensions to be considered.

If I look to sketch 7 it seems to me that I have to consider only dimensions of weld fillet, but, if that's the case, it doesn't make sense to use a hubbed flange.

Any thoughts?

Thanks.

You are using the old edition.

r6155 is correct. See Note (6) in Figure 2-4 in the 2015 Edition - will be on page 376. This should answer your question.
