Dear Members,
I have modeled the existing line as well as the spring support, I have performed the analysis with adding a valve.
I ve checked loads against the applicable code ( NEMA SM23), they still within the allowable.
the spring support could be re-used according to my analysis.
Is there anything ,they have to do in the field regarding the installation of spring can?
I would appreciate any comments.
Sorry for the basic question...we are learning every day.
Thanks in advance.

your saying existing line. first read the existing stress report in that you will find spring rating and spring details apply those information in your current model.

check the Displacement,forces

then perform one more analysis keeping existing line now you check with out entering spring hanger information, keep it default to calculate by CAESAR II.

check the result displacement and forces.

you notice few different in spring loads,forces,displacement

Then come to one conclusion after applying NEMA SM23 code check.
