Magnetic Particle 检查 (MPI)

Magnetic particle inspection (MPI) also known as magnetic particle testing (MPT) is a non destructive test (NDT) method used to check for surface and near-surface discontinuities in ferrous materials. Our magnetic particle testing is performed on-site or in one of our state-of-the-art laboratories. 

Because this method relies on a magnetic field to produce results, it works best on ferrous materials, 像镍, 铁, 钴, 还有一些合金. 钢坯等部件, 酒吧, 铸件, 锻件, 紧固件, weldments and extrusions are also commonly tested using magnetic particle inspection.

Trust the NDT Experts at im体育APP

Magnetic particle inspection can be performed using a wet or dry method, depending on the application. In both methods, the product is electrically charged to create a magnetic field. Then, ferrous 铁 particles are applied to the part in a dry or wet suspension. 

If there is a crack or other defect present, the particles will be attracted to the flaw and build up around the leakage to for an “indication.” The indication is then evaluated to determine the characteristics and cause of the defect. Results allow our 从事专家 to understand the type and severity of any discontinuities on the part’s surface or sub-surface. 

The im体育APP advantage in MPI testing

通过观察自然, location and extent of an indication, our highly trained and experienced inspectors can determine the origin and cause of both surface and near-surface discontinuities. 

im体育APP operates full-service non-destructive testing (NDT) and magnetic particle inspection laboratories that utilize advanced equipment capable of performing quality inspections for virtually any form of ferrous material, 组件或组件.
