Hemi Head attached to Cone
Hemi Head attached to Cone
(OP)
We have a vessel we are analyzing where there is a hemi head attached to a conical shell section. The head has a larger ID than the small end of the cone it is attached to. This was done so that the head is shorter and is close to tangential to the cone. The head comes in with a tangent angle of 39.5° while the cone is a standard 30° half apex. Any advise on how to analyze this? I was thinking of comparing the differential angle based on the delta measurements in ASME Sec. VIII Div. 1 Appendix 1-5.

Nevertheless, you still can use the FEA even if there is an angular mismatch between the cone and the bottom head. Most important, there is no provision in the old cookbook ASME VIII for your configuration, other than the indication to use 'other' engineering methods to design your joint.
