Magnetic Particle Inspection (MPI)
Professional Magnetic Particle Inspection (MPI) services for detecting surface and near-surface discontinuities in ferromagnetic materials without causing damage to the inspected component.
Accurate Surface Crack Detection
Magnetic Particle Inspection (MPI), also known as Magnetic Particle Testing (MT), is a widely accepted non-destructive testing method used to detect surface and near-surface defects in ferromagnetic materials such as carbon steel, alloy steel and iron.
At Om Metalab, MPI testing is performed using proven inspection techniques and internationally accepted standards to identify cracks, seams, laps, inclusions and other discontinuities before they become critical failures.
Our experienced inspectors provide reliable inspection services for manufacturing, fabrication, maintenance and quality assurance across a wide range of industrial applications.
Magnetic Particle Inspection Methods
Depending on the component geometry, material type and inspection requirements, different magnetic particle inspection methods are used.
Wet Method
Fine magnetic particles suspended in a liquid medium provide excellent sensitivity for detecting very small surface and near-surface discontinuities on precision components.
Dry Method
Dry magnetic powder is applied directly to the magnetized surface, making this method ideal for large castings, forgings, weldments and structural components.
Portable Field Inspection
Portable magnetic particle equipment enables on-site inspection of large structures, pressure vessels, pipelines and fabricated assemblies.
Laboratory Inspection
Controlled laboratory testing provides highly repeatable inspection results for production quality control and certification purposes.
Magnetic Particle Inspection Procedure
Every inspection follows a systematic procedure to ensure accurate defect detection, reliable results and compliance with international inspection standards.
- Surface Cleaning & Preparation
- Component Magnetization
- Application of Magnetic Powder or Suspension
- Observation of Magnetic Indications
- Defect Interpretation & Evaluation
- Demagnetization & Final Cleaning
- Inspection Report & Certification
