摘要
海底管道在生产运行过程中容易受到损伤和腐蚀破坏,管壁产生裂纹、点蚀和减薄等危害,严重威胁管道的安全运行,因此对海底管道定期进行内检测成为保障管道安全运行的必然需求。远场涡流无损检测技术是铁磁性管道在役检测的有效方法。本文结合平湖原油立管检测项目的实践,阐述远场涡流无损检测技术的基本原理,总结其优势和局限性,为其今后在海底管道内检测中推广应用提供借鉴。
Some dangerous situation such as damage,corrosion,flaw and wall reduction,etc.often occur on the subsea pipelines in service,so it is necessary to inspect the subsea pipeline periodically.Remote Field Eddy Current（RFEC）Testing Technology is a high-efficiency method for ferromagnetic pipe inline.Through PH oil subsea pipeline project,introduce the basic principle,advantages of RFEC Technology,and provide reference for other projects.
