I am working on a tower line connected to an exchanger. The support next to the exchanger nozzle is getting lifted up. My nozzle qualifies for WRC 107 and is safe with the sustained loads of the system. The hot sustained case loads trouble my exchanger nozzle. Should i go in for a spring instead of a rigid support near the exchanger or should i consider the system to be safe since my nozzle qualifies for the normal operating as well as design condition.
