摘要
针对在常压储罐底板漏磁检测过程中遇到的刮擦、搭接、腐蚀与对接焊缝等典型信号,根据实际经验以及图形显示提出了使用FloormapVS2i软件进行分析的方法和对干扰数据进行删除及调整显示门槛的应对措施,提高了漏磁检测结果的准确性,可以为常压储罐的漏磁检测提供参考。
For typical signals obtained by the tank bottom leakage detection process,such as scratching,lap joint,corrosion and butt welding,based on the practical experience and graphic display,analysis method of using FloormapVS2 isoftware and the counter measures for deleting interference data and adjusting the display response threshold were presented to improve the accuracy of the result of magnetic flux leakage testing.The above mentioned measures can provide the reference for the magnetic flux leakage detection of atmospheric storage tank.
