Study on Crack Leak Quantification of Pressure Pipeline
-
摘要: 在分析泄漏产生的声发射信号衰减特性的基础上,通过压力管道裂纹泄漏试验,标定出信号的距离衰减常数,建立泄漏的声发射信号与泄漏率的关系式。在此基础上,推导出压力管道裂纹泄漏定量计算方法。试验验证表明,该方法能对压力管道裂纹泄漏进行有效的定量估计。Abstract: Based on the analysis of attenuation characteristics of leak acoustic emission signals,the attenuation constant and the correlation with leak rate are obtained by the experiment of pipeline crack leak.The calculation method of crack leak rate for pressure pipeline is presented.The experiment shows that the method is effective for crack leak quantification of pressure pipeline.
