摘　　要：常压金属储罐漏磁检测仪广泛应用于无损检测领域,主要用于铁磁性常压储罐底板的缺陷检测。其使用及检测精度直接关系到能源、化工等行业的生产及运输安全。文章结合检测仪工作原理和检测方法,从个人防护和工作环境两个方面阐述了检测仪使用过程中的关键问题。作为无损检测领域重要的计量器具须进行定期校准,但该类检测仪目前尚无国家、地方或行业检定规程或校准规范,导致校准方法不统一,无法保障量值溯源的准确可靠。通过对漏磁检测仪检测方法的研究,结合仪器原理和计量工作实际,研究了仪器的相关计量特性,给出了测量标准、校准项目和校准方法。The atmospheric pressure metal storage tank magnetic leakage detector is widely used in the field of non-destructive testing,mainly for defect detection of the bottom plate of ferromagnetic atmospheric storage tanks.Its use and detection accuracy are directly related to the production and transportation safety of energy,chemical and other industries.This article combines the working principle and detection method of the detector,and elaborates on the key issues during the use of the detector from two aspects:personal protection and working environment.As an important measuring instrument in the field of non-destructive testing,regular calibration is required.However,there is currently no national,local,or industry calibration regulation or standard for this type of testing instrument,which leads to inconsistent calibration methods and cannot guarantee the accuracy and reliability of quantity traceability.By studying the detection methods of magnetic leakage detectors,combined with instrument principles and practical measurement work,the relevant metrological characteristics of the instruments were studied,and measurement standards,calibration items,and calibration methods were provided.
