| Abstract: | Acoustic emission(AE) technique(AET) is a progressive mature non-destructive testing method, which began in 1960s. AET has been widely used in pressure vessel testing and structural integrity evaluation. The history and the progress of AET for pressure vessel are introduced. AE characteristics of pressure vessel steel and AE testing of pressure vessel are reviewed . The progress of AE instruments, pressure vessel AE testing standards and application are analyzed. At last, the direction of pressure vessel AE testing is on-line monitoring, pattern recognition and artificial neural network pattern recognition analysis of AE signals. |
