This contribution is devoted to causes of damaging tube bundle by fluid flow between tubes with U-bends inside a process boiler. Tube bundles are commonly used in process industry for heat transfer. Use of U-bends allows efficient space utilization and thermal dilatations of the bundle are compensated. Design of a tube bundle is strictly controlled by thermal-hydraulic design and strength design. Strength design includes flow induced vibration evaluation, which is done using simplified methods and cannot substitute fatigue assessment. This contribution studies influence of the fluid flow on the cyclic fatigue of the U-tube bundles.
