Magnetic Particle Inspection
Magnetic particle inspection (MPI) is an effective and reliable non-destructive testing method that is widely used for verifying the reliability and durability of materials. After proper surface cleaning, MPI makes it easy and efficient to detect surface-open or near-surface discontinuities such as cracks and other anomalies in solid materials, contributing to a longer lifespan for materials and to the improved efficiency of industrial processes.
MPI is based on electromagnetism and on exploiting the properties of ferromagnetic materials. A magnetic field is applied to ferromagnetic materials, and the object under examination is then dusted with a fine magnetic powder. The powder accumulates in areas with cracks and defects, making these problem areas visible. Based on the visual pattern, it is easy to determine whether there are cracks or defects in the material being tested.
MPI offers a number of significant advantages over traditional testing methods. It is not only a non-destructive method but also possesses exceptional sensitivity for detecting minor cracks. In addition, the method is fast and efficient, allowing larger surfaces to be examined in a single step, and the results can be evaluated immediately.
Magnetic Particle Inspection is widely applicable across various industries, including steel manufacturing, mechanical engineering, and the oil and gas industry, specifically including steel structures, pipelines, pressure vessels, tanks and rotating machinery components. The method helps improve material reliability and enables the early detection of defects and cracks, thereby reducing the risk of structural failure and extending lifespan.
