Dear All,

We are designing a flange as per appendix 1-6 Loose Flange Type Fig:1-6 skecth (a).

I am considering the flange as a loose flange with a hub. So the allowable stresses are hub stress,radial and tangential stress.

I am using skecth Fig 2-4 (4a).

Also as stated in code in 2-7 CALCULATION OF FLANGE STRESSES

" (a) for integral type flanges [Fig. 2-4 sketches (5), (6), (6a), (6b), and (7)], for optional type flanges calculated as integral type [Fig. 2-4 sketches (8), (8a), (9), (9a), (10), (10a), and (11)], and for loose type flanges with a hub which is considered [Fig. 2-4 sketches (1), (1a), (2), (2a), (3), (3a), (4), (4a), (4b), and (4c)]: "

is my methodology correct? Please help.
regards
