Abstract

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.
