Abstract:

Through the stress review, pipeline vibration measurement and analysis on the main steam pipeline in a power plant, the vibration characteristics of the main steam pipeline are obtained. According to the vibration measurement results, a treatment scheme which is installing a damper on the main steam pipeline of max vibration is proposed. It effectively eliminates the pipeline vibration and provides a solid guarantee for the safe and stable operation of the unit.
