摘　　要：与传统的储罐底板检测方法相比,AE检测方法是一种在线、高效、经济的检测方法,不需要清罐、置换、打磨,短时间内就可对罐底板整体完成检测。文中利用声发射(AE)检测技术,实现了对大型原油储罐底板腐蚀状态的在线检测。利用AE设备及传感器探测、记录、分析,进而判断声发射源,获取底板腐蚀状态的相关信息,通过分析事件定位及通道撞击图,结合AE特征参数,从而判定储罐底板所处的腐蚀活性状态。Compared with the traditional method of tank floor detection,the AE detection is an on-line,efficient and economical method.It doesn’t need to clear the tank,replace,grind and can complete the test of the whole tank floor within a few hours.In this paper,by using AE detection technology,the on-line detection of corrosion state of large crude oil tank floor is realized.AE equipment and sensors are used to detect,record,analyze the sound emission source,and so to obtain the related information of the corrosion state.Through the analysis of the location map of the events and the impact map of the channel,and the combination of the AE special characteristic data,So as to determine the corrosion active state of the tank floor.The corrosion mechanism of crude oil storage tank in service is analyzed.The results show that AE detection technology can accurately realize on-line corrosion detection of tank bottom plate,and can provide corresponding countermeasures for later tank use and maintenance.
