ASME DIv. 1 vs Div. 2 Flange Stress Factor?
ASME DIv. 1 vs Div. 2 Flange Stress Factor?
(OP)
Hi I have an excel program to do Appendix 2 flange calculations. I have read that Div. 2 2010 includes external loading into its calculations and I would like to integrate that into my spreadsheet. Most equations are the same but I have noticed that V = flange stress factor / factor / hub factor for integral type flanges is different from Div. 1 and Div. 2. I appears that the Div. 2 committee has just run a curve fit to try to simplify the Div. 1 calculations for V, can someone confirm this? Also Div. 2 limits V for h/ho values of 0.1 to 2 which is not in Div. 1 does this matter?

I did compare the two but noticed outside the h/ho range there was a large difference between the Div. 1 and 2 equations. Within the range they are fairly close as you have noted.
