AW: Limit stop in Piping stress analysis

Man,

What are you upto. Any way, just to remind you that the golden rule in piping analysis is to provide only one limit stop (or axial stop) in a straight pipe run unless you have an expansion loop in between. In your analysis please check if the line is balanced in expansion sress. In my opinion the line is already overstressed.

I am unable to understand your "distribution of piping loads" concept. In any case if the line is hot and there is a long straight run, try using an expansion loop with two limit stop at suitable positions on either side.

In a straight pipe run how many limit stops we can provide.

I have designed test model wherein I have put three limit(axial) stops(with equal and unequal gaps) in straight run to distribute load on three supports but in operating case last axial stop is acting while other two stops are not acting during operating case.
What would be the reason for this phenomena? Thanks
Hitesh
