Magnetic Particle Testing (MT), also referred to as Magnetic Particle Inspection (MPI), is a non-destructive examination method used to detect surface and near-surface discontinuities in ferromagnetic materials such as carbon steel and alloy steel. The method is highly effective for identifying defects including cracks, seams, laps, and inclusions that may compromise structural integrity or service performance.
Various MT techniques and methods may be used depending on the application and inspection requirements, including visible or fluorescent particle inspection, dry or wet particle methods, and AC or DC magnetization techniques. These methods allow inspections to be performed effectively across a wide range of materials, component geometries, and service conditions
At IntegriTest, Magnetic Particle Testing services are provided to support quality assurance and asset reliability across industries such as oil & gas, construction, manufacturing, pipelines, shipbuilding, and heavy industrial applications. The inspection process involves magnetizing the test material and applying magnetic particles to the surface, allowing discontinuities to become visible through magnetic flux leakage indications.
MT is widely used for the inspection of welds, pressure vessels, structural steel, lifting equipment, piping systems, and mechanical components due to its speed, reliability, and cost-effectiveness. Inspections are performed by personnel certified to CGSB 48.9712 standards, in accordance with applicable codes and standards including ASME, ASTM, CGSB, CSA, & AWS requirements using calibrated equipment and approved procedures.
Through accurate defect detection and professional inspection practices, we help clients improve safety, maintain compliance, and reduce the risk of component failure and unplanned downtime.
MT/MPI is suitable for ferromagnetic materials including carbon steel, alloy steel, welds, castings, forgings, and other steel components.
