Is WRC 107 Applicable on Tangential Nozzles ?

Is WRC 107 Applicable on Tangential Nozzles ?

Is WRC 107 Applicable on Tangential Nozzles ?

(OP)
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,

RE: Is WRC 107 Applicable on Tangential Nozzles ?

Generally, the answer is "no" and "no".  WRC 107 and WRC 297 are set up for radial nozzles only.  If the nozzle is only slightly hill-sided, they should be a good approximation for it.  Otherwise, you're probably looking at a FEM problem to determine stresses.  I don't know if any of the normal vessel software includes that kind of analysis.

There is also a "Boiler and Pressure Vessel Engineering" forum, you might check there as well.
