Hi,
I am doing a stress analysis of an existing line (10" pipe) in which is getting vibrated. The line is connected to vertical equipment in which the equipment has a design temperature is 50 degree Celsius and the line has -101 degree Celsius. At a point on pipe support taken from the vessel, the pipe gets displaced up to 27 mm upwards on node 235. I have considered only guide support at node 235 in axis (X & Z). Here I am not considered rest support.

• Do I need to provide a spring support at that point node 235?

• If I provide the spring support on 235 node the piping system get vibrate or not.
