Magnetic Particle Inspection – Best NDT Inspection

At Best NDT Inspection, we specialize in Magnetic Particle Inspection (MPI)—one of the most effective Non-Destructive Testing (NDT) methods for detecting surface and near-surface defects in ferromagnetic materials. This technique is widely used in industries such as aerospace, automotive, oil and gas, and construction to ensure structural integrity and safety.

What is Magnetic Particle Inspection (MPI)?

Magnetic Particle Inspection is a non-destructive testing technique used to detect cracks, fractures, and other discontinuities in ferromagnetic materials. The method involves magnetizing the test specimen and applying finely divided magnetic particles to the surface. If there are any surface or near-surface defects, the particles accumulate at these locations, creating a visible indication of the flaw.

How Does Magnetic Particle Inspection Work?

1.       Surface Preparation: The component is cleaned to remove dirt, grease, or any other contaminants that may interfere with the test.

2.       Magnetization: A magnetic field is applied to the material using either direct or indirect magnetization methods.

3.       Application of Magnetic Particles: Dry or wet magnetic particles (usually iron oxide-based) are sprinkled or sprayed onto the surface.

4.       Detection of Defects: If a defect is present, it disrupts the magnetic field, causing the particles to gather at the location of the discontinuity.

5.       Inspection and Interpretation: The inspector examines the accumulation of particles under appropriate lighting conditions or UV light (for fluorescent MPI) to determine the severity of the defect.

6.       Demagnetization and Cleaning: After the inspection, the component is demagnetized and cleaned to remove residual particles.

Advantages of Magnetic Particle Inspection

·       High Sensitivity to Surface Defects: MPI can detect small cracks, seams, and other defects that may not be visible to the naked eye.

·       Quick and Cost-Effective: The process is relatively fast, making it suitable for high-volume inspections.

·       Portable Equipment Available: MPI can be performed in laboratories or on-site using portable testing kits.

·       Immediate Results: Indications appear almost instantly, allowing for prompt evaluation and corrective action.

·       Applicable to a Wide Range of Industries: It is widely used in welding, manufacturing, pipelines, aerospace, and marine sectors.

Industries That Rely on MPI

·       Aerospace: Inspection of aircraft engine components, landing gears, and turbine blades.

·       Automotive: Detecting cracks in engine parts, axles, and gears.

·       Oil & Gas: Inspection of pipelines, pressure vessels, and drilling equipment.

·       Manufacturing: Ensuring quality control in welded structures and machined components.
