双铰链型蒸汽管道补偿器失效原因分析及改进

Analysis of Failure Cause of Dual Hinge Type Steam Pipe Compensator and Improvement Measures

介绍了蒸汽管道补偿器的几种类型以及波纹式补偿器的几种结构形式,以及造成铰链型补偿器失效的两种原因,一种是补偿器由于结构问题造成的受力稳定性的破坏;另一类是补偿器材质的选择,并从这两方面进行了改进。

Several types of steam pipe compensator and several structure forms of bellows type compensator are presented.The two causes resulting in failure of hinge type compensator are: damage of stress stability caused by structure of compensator;and selection of compensator material.The improvement measures are implemented.
