The Application of Acoustic Emission Inspection of the Oil Tanks Covered By Soil

摘要: 为了给油库管理者制定油罐检修计划提供科学依据，对覆土油罐进行了声发射检测试验。探讨了覆土油罐声发射技术的应用方法和数据分析，得到了试验油罐底板腐蚀程度和声发射信号能量分布的情况。试验结果表明，声发射技术能够对覆土油罐底板的腐蚀状态做出判断，且静压检测和升压检测都可以反映出覆土油罐底板声发射源的活度差异，并据此确定储罐维修的优先权。

Abstract: The acoustic emission inspection experiments of the oil tanks were conducted to offer a scientific overhaul plan for oil depot directors. Through discussing the application method and the data analysis of AE inspection, the corrosion degree of bottom plates and the energy distributions of AE signals were acquired. Thus a conclusion was drawn that both AE static test and loading test could reflect the differences of the AE activity in the bottom plate of the tanks, and hence determine the priority of repairing the tanks.
