Acoustic Emission Testing for New Hydrogenation Reactor During Water Pressure Experiment

  • 摘要: 为发现新制压力容器的先天性活性缺陷,提高制造质量,对一台新制加氢反应器水压试验过程进行声发射检测。采用三角定位与线定位结合的方法,对加氢反应器壳体和接管进行了整体检测。采用二次加载的方式,重点分析第二次加载过程和保压阶段的声发射信号。检测过程共发现3处有效声源,通过采用超声波和渗透探伤方法进行复验,确定声源S1为流动噪声;声源S2为鞍座与筒体间的机械摩擦信号;声源S3为弯管内堆焊层表面缺陷。该检验实例可为新制容器出厂前的全面检验提供借鉴。
    Abstract: In order to find congenital defects in new pressure vessels in time and improve containers manufacturing quality, a new hydrogenation reactor during water pressure experiment with acoustic emission technique was tested. Using triangulation and line positioning method, the hydrogenation reactors shell and pipe was detected in whole. Focus was put on monitoring acoustic emission source localization signal in the second loading cycle and packing phase. During the testing process 3 effective acoustic sources in total was discovered. Through using ultrasonic test and liquid penetrant test in foundation of acoustic emission testing, result was assurance as follows: acoustic sources S1 was the flow noise, acoustic sources S2 was the mechanical friction signal between saddle and cylinder while loading, acoustic sources S3 was surface defects in bent pipes layer. This instant testing could offer a reference to new manufacturing pressure vessels before leaving the factory.
