WRC 107
(OP)
Hi All,
Regarding WRC calculation i have a question: please consider a 4" nozzle on a vessel including 4"pipe attached to shell, 4x2 reducer and 2" flange. To check the WRC for this nozzle should i consider the allowable nozzle load applicable for 2" size or 4"?
Thanks in advance

RE: WRC 107
first of all the nozzle is connected to a process pipeline of 2" and consequently the nozzle will be subjected to a nozzle loads due to the related connected pipeline.
As I know, the main problem relating to your matter is about the nozzle shape where the conical transition cannot be considered into the WRC calcualtion.
Anyway please consider that the allowable nozzle load used in WRC calculation are related to a pipeline of 2", while the nozzle neck to shell attachment is 4". Therefore the only concern can be the behavior of the conical transition subjected to load combinations.
