Dear Mr.Richard Ay,

I am also one of the person about to ask the same query. Why the flange leakage analysis is not available for dynamic check.

Since most of my pipeline stress analysis are concerned with the pumping station with flange connections and these lines are to be designed for water hammer case.

Even in the static case, for a long pipeline, when the flange connections are near to the anchor point, the axial load on the flange is huge and it is advised to the pipeline designer to locate the flanges far away from the anchor.

Since the static case affects the flange connection much, why not it might have got affected much in the dynamic effect !!!!!!!

But there is no flange leakage check in Caesar-II for dynamic effect.
