The influence of vibration on No.1 steam extraction pipeline in the power plant was investigated by on-site vibration test and numerical simulation. The grade and reason of vibration were discussed. Finally, the problem was solved through using viscous damper. The damper which reduced the effect of itself on structure to a minimum level was also conve-nient, compared with other different kinds of devices. Significantly, other plants could learn from this case.
