Magnetic Flux Leakage and Acoustic Emission Testing Technique for Atmospheric Storage tanks
In china, atmospheric storage tanks are not included in the management of special equipment, and therefore they are not required to be inspected compulsorily. There is larger difference between China and developed countries on atmospheric storage tank inspection technique than the other techniques on the inspection of pressure vessels. It is widely believed that the strength worsening and perforation of the tank is mainly caused by the serious corrosion at the bottom surface of tank floor. The present development of nondestructive testing on atmospheric storage tank was analyzed systematically in this paper, in which the principle, present status, the usage of inspection equipments and the application of the magnetic flux leakage testing and acoustic emission testing techniques on atmospheric storage tanks were mainly introduced. The problems existing in the inspection equipments usage were discussed. A practice for inspecting and evaluating atmosphere storage tanks using these testing methods was proposed.
