Comparative Analysis between Acoustic Emission Testing and Magnetic Flux Leakage Testing
Storage tanks are used as the main equipment for storage of petroleum and petrochemical raw materials and products, and are widely used in petroleum and petrochemical enterprises. Safe operation of storage tanks is the premise to ensure the normal production of enterprises. In recent years, in accordance with the requirements of the Safety and Environmental Protection Department of the group company, a large number of on-line acoustic emission testing testing has been carried out in our institute. At the same time, Magnetic flux leakage testing of some storage tanks is carried out according to the actual situation, and the comparison is made in depth. The results show that acoustic emission testing can well reflect the corrosion of tank bottom and can provide decision support for the daily management and maintenance of tanks.
