thickness of small hub end of flange - UG 27 C-1 - 02/04/10 09:54 PM
Dear all
While design flange calculation as per Appendix 2, one need to use lower allowable stress in case of ASS material (code gives two values one bsed on 90% and another twp -third of yield).
As per code one has to use lower allowable stress for flange design as per Appendix-2. However when thickness at small end is calculated as per UG-27-C, one can use higher allowable stress based on 90% yield.
But PV Elite uses lower allowable stress while using t= PR/ (SE-0.6p) for hub smaller end. Can some body comment on the same
Thanking You and With regards
