"1) run an analysis without pressure to get the flange load excluding the pressure term":

so i obtain flange load caused by thermal cases only.



"2) model the pressure distribution between the XJ and flange by hand " and then "i would specify the P*A(in).........":

to model pressure distribution i insert the 3 forces (1 on elbow and 2 on the EJ sides) but i DON'T set any line pressure inside pipe AND no "Effective Diameter" specified for expansion joint. Is it right?


otherwise, i will have again the pressure contribution (coming from EJ) acting on flange that should really act on pump wall. is it right?
