Rectangular flange design

[flaka]

Need to calculate a rectangular flange.
Currently I use the HEI method, for full-face flanges.

I've seen on the forum that others use:
Marbec method called Nodal Circle Method
BLACH

Where can i find this methods?

thanks.

I am facing the same situation but I don't know the HEI method.
Do you know where can I find it?


Thanks
