The invention relates to the technical field of pipeline detection equipment, and particularly discloses a magnetic
hydrogen coupling multi-
physical field test device for
hydrogen embrittlement assessment, which comprises a test
bed, a pipeline mounting
assembly, a torsion driving mechanism, a stretching driving mechanism and a
magnetization detection mechanism, the test
bed is provided with a flat table board with a sliding rail
system, the pipeline installation
assembly is provided with a fixed part and a movable part and arranged on the sliding rail
system at intervals, the fixed part is fixed to the sliding rail
system, the movable part slides along the sliding rail system, and the two ends of a to-be-tested pipeline are installed on the fixed part and the movable part. The torsion driving mechanism is slidably mounted on the slide rail system and is used for driving one end of the to-be-tested pipeline to twist axially; the stretching driving mechanism is slidably mounted on the sliding rail system and used for stretching the end, close to the movable part, of the to-be-tested pipeline. The
magnetization detection mechanism comprises a laminated
magnet yoke
assembly arranged on the to-be-detected pipeline in a sleeving mode and a magnetic detection sensing assembly for collecting magnetic signals of the pipeline, the
magnetization detection mechanism is installed on the sliding rail system in a sliding mode and slides between the fixed part and the movable part, and the fitting degree of the detection result and the actual working condition is improved.
