Valve with elliptical body/bonnet connection

[alby87]

Good morning,
Exist some standards (like ASME, API) with reference to calculation for valve with elliptical body/bonnet connection..
my problem is that in the elliptic flange it's difficult to consider a bolt circle diameter (instead in the circular b/b connection there are a unic bolt circle diameter). so i have some trouble to calculate the stress on the body as per ASME VIII division I Mandatory apppendix 2.
so i ask if exist other standards or some reference to deviation fron the ASME,
Thank you

Kennedy Valve were pioneers in elliptical connections; maybe their engineers can help you out. ¡Que tengas mucha suerte!
