Dear Habib,

I do not want to discuss a hypothetical problem.We can have as much garbage as we wish.But,please share your self experiend practical problem while working for a reputed client where you have actually faced this situation.Then the issue will over and I will agree with you in totality with humility.

I am unable to convince you that WNC load case is not used for nozzle evaluation.

Any other gentllmen here,could you please help to address this issue more clearly.

I have started by responding to following reply

"I think WNC case is for to address spring upward load issue. Sometime spring support is used closer to equipment nozzle to minimize operating load at nozzle. When plant is shut down or line is not in operation with no fluid inside spring may produce unacceptable upward load on nozzle"

And I do not know what wrong with this...........

"I do not know where from you draw conclusion no need for sustain load check

***3)It does make a sense to evaluate nozzle in sustained load case?????.***"

Aslam
