Flange design gasket oustide studbolts
(OP)
Hi,
need to design a bolted flange with the gasket outside the boltcircle.
It can't be a full face gasket, it is a flat metal jacketed gasket.
Anyone?

Anyway I think that you should be able to use App.2 of Div.1 without changes, some lever arms will be negative and you should conserve the sign in the equations.

Indeed an unusual setup.

This is done for a "pull through floating head".
Like a tema head type: "t".

These are used on floating head heat exchangers (TEMA "S" and "T") where the tube side has only one pass.

You could see it as a regular loose type flange (type 2.4) but with the gasket outside the bolts & the flange is positioned in the middle of a pipe.
The process fluid is around the flange and pipe.

might be handy if you have to come up with your own eq's.
RE: Flange design gasket oustide studbolts
This flange pair could be considered to be subject to external pressure, and thus calculated per 2-11, but, as the gasket is outside the bolt circle, it behaves like a flange subject to internal pressure, with all three loads HD,HG,HT acting in the same direction, thus adding up in the moment equation.
In my opinion, changing my position with respect to my previous post, you should calculate flange moments per 2-6 using hG=(G-C)/2 and M0=W(G-C)/2

Can you use a metal/metal contact for sealing?
