Hi,
I'm designing a horizontal vessel acc. to ASME VIII Div.1. This vessel has 2 cylindrical shells circunferentially welded, each of those length 1,5m (total 3m).
At the left and right ends of this vessel there are 2 reduction cones from plate and then WN flanges welded to them with their blind.
Material: 316, MDMT 0°C, design pressure 7,5 bar, O.D. 508mm
This vessel is supported by 2 saddles (1 sliding + 1 fixed) with wear plates. The 2 saddles are at the same distance from the end of the 2 shells/cones and they are "symmetric".
Now, I'm trying to design the saddles acc. to ASME VIII Div.2, but I don't understand what "Stiffened Vessel Length" is. It's a parameter required by my calculation software and it corresponds to symbol "L" in nomenclature list, par. 4.15.6 of Div.2. In this case what length do I have to use? The total length of vessel, including cones+WN? Or only from W.L. to W.L. of cylindrical shells themselves?
Thank you
