Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to an MT magnetic powder detection tooling for super-long round tubes. Background Art

[0002] MT magnetic particle testing, also known as magnetic particle inspection, is based on the principle of using magnetic particles as a display medium to detect defects in materials. This method applies a magnetic field to the material being tested, causing the magnetic particles to adsorb at the defects. The presence of defects in the material is then determined by observing the magnetic particles' display.

[0003] After searching, a Chinese patent with publication number CN220872409U discloses an O-type probe for magnetic particle detection. The utility model drives the threaded sleeve to rotate by rotating the fixing rod, and drives the threaded support rod to adjust the height, so that the body of the component to be tested is located in the middle of the probe connection shell, and then the threaded limit rod is turned to push the clamping plate to clamp the body of the component to be tested on the upper part of the placement plate. By stably fixing the body of the component to be tested between the probe connection shell, it is convenient to stably fix the body of the component to be tested, thereby performing stable flaw detection on the body of the component to be tested, and improving the stability of the detection of the body of the component to be tested.

[0004] However, due to the influence of the environment, impurities are generally adsorbed on the surface of the test object. These impurities will interfere with the detection and affect the visibility of the detection. It is necessary to carefully observe these magnetic traces to find potential defects and problems. Therefore, a new solution is needed to solve this problem. Utility Model Content
