I took a careful look at the output from PVElite for vacuum stiffener rings. I was surprised not to find an analysis of the strength of stiffener ring attachment loads per ASME VIII, Div 1, paragraph UG-30(e) and example L-5 of Appendix L.

Is PVElite considering adding this calculation?

:rolleyes:

Tom,

The CodeCalc portion of PVElite has always provided this functionality. As of verison 5.0, the integrated portion of PVElite also performs the stiffening ring weld calculations per UG-30.

Thanks Ray

These calculations in PVElite will be very helpful. When will Ver 5 be available to the users?

Thanks & Best Regards
