Acoustic Emission Test of Leakage in Jacketed Structure Inner Pipe

For the timely detection of jacketed reactor structure on the pressure changes in the process of the inner pipe leakage,a jacketed structure inner pipe leakage acoustic emission detection system was established in the laboratory.Through the comparative analysis on the determination of the parameter analysis method,the spectrum and RMS distribution of leakage acoustic emission signal was researched,hence providing experiment basis for field test.
