Nozzle at Cone End
Nozzle at Cone End
(OP)
Hello,
I have a nozzle at hopper(Cone end) facing bottom. Does WRC 107/297 is applicable to check the nozzle loads. If not how to proceed further

In the first case you are loading only a small portion of the surface of the shell. This results in through-thickness bending, etc. The WRC bulletins provide for this type of analysis.
In the second case you are loading the entire circular cross-section of the cone with resulting longitudinal stresses due to axial load and bending moments, and some shear loads. This case is actually treated quite simply. You have a beam (or a beam-column) of circular cross-section. You can find the stress by elementary formalas like M/S (bending moment / section modulus), P/A (axial load on "column" / cross-sectional area), etc.

The vessels were designed in 40's and 50's and have been in cyclic service since. All the calculations for these vessels were done Sect VIII Div 1. They have been verified many times over the years.
I'll call tomorrow to see if I can get the calculation format as I know right where they are located if the records people haven't tossed them.

The weldneck vessel/head flange was the first calculation done when we got Compress. There was some question as to the hub length.

I thought that you might have been talking about a conical shell, with a nozzle IN the conical shell, that is oriented parallel to (but offset from) the axis of rotation of the conical shell.
