漏磁检测技术在大型原油储罐底板上的应用
Application of Magnetic Flux Leakage Technique on Atmospheric Tank
摘 要
讨论了漏磁检测技术在大型原油储罐底板检测中的应用，分析了影响漏磁检测信号的主要因素。利用FloormapVS2i漏磁检测仪对某10万m3原油储罐进行检测，给出了储罐底板的整体状况图。对整体状况图进行分析与缺陷识别，并通过超声波测厚仪对检测结果进行复验，证实了漏磁检测方法的可靠性。以漏磁检测方法为主，配合其他检测方式，可准确有效地评定储罐底板安全状况，为储罐的安全运行提供保障。

Abstract
The application of magnetic flux leakage(MFL) technique on atmospheric tank was introduced, and its main influencing factors were analysed. A storage tank which is about 0.1 million m3 in volume was inspected by FloormapVS2i, after which the overall diagram of the tank bottom by MFL was obtained and presented, then the defects were analyzed and rechecked by ultrasonic thickness gauge. It suggests the magnetic flux leakage technique together with other nondestructive technique, such as ultrasonic testing, penetrate testing, can evaluate the condition of tank bottom accurately and efficiently, which ensures its safe operation.
