The main obstacle which prevents the rapid spread of Acoustic Emission (AE) testing on refinery structures in Russia is the complexity of this NDT tool. The lack of well- defined methods of data analysis and the huge amount of AE data collected within each test are the major problems. The possibility of mistakes in a period of testing and data analysis leading to erroneous conclusions related to the condition of the structure sometimes negatively affects the image of the AE method. However, the correct application of AE can bring unique opportunities in the inspection of structures in the industry. Some examples of successful applications and the unique possibilities of AE testing are presented in this paper.
