海洋石油钢结构在建造过程中非常复杂,其所面临的环境异常恶劣,且钢结构在石油平台建造上发挥重要技术。采取高效方法对海洋石油钢结构进行检验,能够提高钢结构质量得以提升。在本文研究中对湿式连续磁轭法在海洋石油钢结构中的运用情况进行分析,且能够从海洋石油钢结构实际运营能够中去感应磁场路径所存在的距离,且磁轭与工件接触耦合过程中所存在的灵敏度,以此能够对磁粉检验提供一定借鉴。 Offshore oil steel structures are very complex during construction and their environment is extremely harsh and steel structures play an important role in the construction of oil platforms. To adopt an efficient method to test the offshore oil steel structure can improve the quality of the steel structure. In this study, we analyze the application of wet continuous yoke method in offshore oil-bearing steel structures and can sense the distance existing in the magnetic field path from the actual operation of offshore oil-bearing steel structure, and the yoke-workpiece contact-coupling process In the presence of the sensitivity, in order to be able to provide a reference for magnetic particle testing.
