Hi,
We have a 6 inches line connected to a heatexchanger. The line vibrates visibly. Natural frequency of the system was calculated and it is 3.34 Hz but the system fails in thermal loading, since temperature is 150 degree C. Nozzle loading also increases than designed for heatexchanger, i.e 1800 N.m.
Any help would be appreciated for arresting vibrations.
