Research on Leakage Detection Technology for Crude Oil Storage Tank
The most likely to appear failure form for crude oil storage tanks in complex internal and external environments is the perforation of bottom plate,resulting in crude oil leakage.The application of acoustic emission method and magnetic flux leakage scanning method to the leakage detection of the storage tank bottom plate was introduced in this paper.Both methods could evaluate and locate damage to the bottom material and microleakage of the baseplate material.The principle of leakage detection for crude oil storage tanks was introduced,and the field detection process was analysed.After the acoustic emission and magnetic flux leakage scanning detection of the same crude oil storage tank were carried out,the two detection results were analysed and compared economically.And then the integrity assessment of the storage tank was given,and the maintenance opinions of the storage tank were given.
