Through site investigation and stress check, the vibration characteristic of feed water pump’s inlet pipeline was mastered. After the analysis of the results, a preventive scheme was worked out, that formulated technical solutions to adjust the original piping horizontal limit supports, and increase conditional limit supports. The scheme signiifcantly reduced pipe vibration level, and improved the pipeline stiffness after adjustment.
