摘　　要：三轴高清漏磁检测技术成功解决了老管道的焊缝检测难题,但随着老管道的逐步退役,对于新管道是否需要三轴高清漏磁检测技术成为技术人员和管理人员较为关注的问题。通过对比三轴高清漏磁内检测与传统漏磁内检测的技术优势,重点探讨了老管道与新管道本体所面临的主要风险以及对于三轴高清漏磁检测的需求。提出应该进一步加强三轴高清漏磁内检测技术的研究与应用,以期能够更加精确地检测管道缺陷,为管道后续的完整性评价提供可靠的数据参考,确保管道本质安全,对管道运营者的管理决策具有重要意义。Three-axial high-resolution magnetic flux leakage （MFL） inspection technology is successful in weld inspection on aging pipelines. But with the gradual decommissioning of aging pipelines, technical and management staff focus much on whether this technology is needed for newly built pipelines. In this paper, the principal risks related with the main parts of aging and newly built pipelines were mainly discussed, and the requirements for three-axial high-resolution MFL inspection were analyzed through comparison of technical advantages between three-axial high-resolution MFL internal inspection and conventional MFL internal inspection. It was recommended to enhance the research and application of three-axial high-resolution MFL inspection technology, so as to make pipeline defect inspection more accurate, provide reliable data reference for subsequent integrity assessment and ensure the intrinsic safety of pipelines. In addition, it has great significance to management decisions of pipeline operators.
