Abstract: This paper briefly introduced the working principle and technical features of acoustic emission. A scheme of the planar location of AE test was proposed according to the structural characteristics of oil and gas separators,and the preparation work before a test was introduced. Trough loading and test twice,and comparing the collected data,the author has comprehensively analyzed the noise source in test with the principle of Kaiser effect. It pointed out that the effective signals should be picked up from the data acquired at the pressure holding stage,and the nature of defect should be determined on the basis of them. Finally,it gave the test results and put forward the problems which urgently need to be solved in present and the direction of future work.
