Re: Limit stop in Piping stress analysis

Dear Steve,

I did not get you exactly.

What I think, it can not be possible with rigid restraints. In case of rigid restraints the line would be overstressed due to not allowing thermal expansion. In case of multiple restrictions in a straight line, The supports can be sheared off or it can damage the pipe as well.

With rigid supports, we can achieve the distribution of load theoretically, as suggested by Tushar, but this system will be very very difficult to be implemented at site. And more over, the performance of the system could not be evaluated exactly due to deviations at site.

I case of springs, being the low stiffness, supports absorb the thermal expansion of the line and reduce the thermal stresses. But this certainly can not work with conventional rigid limit stops.
