Magnetic Particle Inspection (MPI)

Superior Surface Flaw Detection

Magnetic Particle Inspection (MPI) is a non-destructive testing technique used to detect surface and near-surface imperfections in ferromagnetic materials. At Interprovincial NDT, we utilize MPI to provide quick and accurate inspections, ensuring that your equipment and components are free of defects that could lead to failure.

What is Magnetic Particle Inspection?

Magnetic Particle Inspection involves the application of magnetic fields to ferromagnetic materials to detect discontinuities. The process includes magnetizing the material and then applying ferromagnetic particles to the surface, which are attracted to areas of flux leakage, highlighting the presence of any discontinuities.

How Does Magnetic Particle Inspection Work?

The MPI process starts by inducing a magnetic field in the component being inspected. Any surface or near-surface discontinuities will disturb this magnetic field, causing leakage. Magnetic particles, either dry or suspended in a liquid, are applied to the surface; these particles accumulate at areas of flux leakage, visibly outlining the flaw. This method allows for immediate identification of defects such as cracks, seams, or inclusions.

Applications of Magnetic Particle Inspection in Industry

Magnetic Particle Inspection is crucial in industries where the integrity of metallic components is essential. It is widely used in:

Automotive for critical component inspection
Rail and shipping for checking integrity of axles and rails
Construction for structural steel inspections
Manufacturing for quality control of machinery and equipment

Advantages of Choosing Magnetic Particle Inspection (MPI)

MPI is preferred for its speed and effectiveness in identifying surface flaws in ferromagnetic materials:

Sensitive to Small Defects: Capable of detecting extremely fine surface disruptions.
Rapid Results: Allows for fast processing and immediate results, ideal for high-volume or critical inspections.
Simple Visualization: Directly shows the defects on the material’s surface.
Cost-Efficient: Reduces the cost and time associated with preventative maintenance and unplanned downtimes.
