Magnetic particle detection is a non-destructive testing method that uses magnetic powder to form magnetic powder images on the surface of materials to detect surface and near-surface defects. Magnetic particle flaw detection is also widely used in the quality inspection of flange forgings of petrochemical ring parts. In this paper, the application of magnetic particle flaw detection for flange forgings of petrochemical ring is discussed.
The basic principle of magnetic particle inspection is to use magnetic powder to form magnetic powder image on the surface of the material to detect the defects on the surface and near the surface of the material. When there are defects on or near the surface of the material, the local magnetic field will change, resulting in the formation of magnetic powder images on the surface of the material. Through the analysis of these magnetic powder images, we can judge whether there are defects on the surface or near the surface of the material and their size and location. Therefore, magnetic particle flaw detection has the advantages of high detection precision and no damage to materials, which is of great significance in the quality detection of flange forgings of petrochemical ring parts.
