I have a tangential nozzles welded to a pressure vessel.

I have to calculate the local stresses at nozzle / shell interface. Is WRC 107 applicable for tangential attachement ?

If not, is there any other easy way to determin local stresses.

Thanks,

There was a typo on subject line. It should have read 'Is WRC 107 applicable on Tangential Nozzles ?'
 
PD 5500 Appendix G may help you. It is similar to WRC 107.

It has rules for long doubler pads (which is similar a to tengential nozzle). You'll have to put your thinking hat on and read the appendix carefully to decide if your tangential nozzle is equivilant to a long doubler pad.
