Hi all,

I need help with this analysis:

I've the following displacement (as for attachment) and in the EXPANSION case the small tube (1,5" SCHEDULE std) doesn't match B31.3 requirements.

This is due to the fact that the diaplcement on the top (220 mm INLET DISTIBUTOR MOVEMENT) is lesser than the diplacement of the flex. tube (+245 mm) ----> the loop is overstressed due to high bending moment.

Any solution to solve this problem?
