The finned tubes above the air cooler in the refining unit exhibit shaking
Is it the air-cooled tube bank vibration or the louver vibration? Tube bundle vibration will definitely have an impact. If the tube bundle and tube sheet are welded, cracks may appear in the welds ； If it is crimped, it will cause looseness at the joint. A leak has occurred
The flaps moving only affects heat transfer.
Vibration can cause metal fatigue, and over time, fatigue leads to fracture
