MPI in Detail

Magnetic Particle Inspection (MPI) is a fast and effective non-destructive testing (NDT) technique used to locate surface and near-surface discontinuities in ferromagnetic materials like iron, steel, and nickel alloys. It is particularly valuable for identifying cracks, laps, seams, and fatigue-induced flaws in welds, machined parts, and structural components that are often subject to cyclic stresses and harsh environments.

At 2R Inspection, we offer both wet and dry MPI methods, using fluorescent or visible magnetic particles depending on the application and visibility needs. Our certified inspectors follow internationally recognized standards such as ASTM E709 and ISO 9934 to ensure precision and consistency. The process involves magnetizing the component, applying magnetic particles, and observing the patterns formed by any leakage fields at defect sites. We serve a wide range of industries — from oil and gas to heavy machinery — ensuring critical components are safe, durable, and fit for service. With 2R Inspection, MPI becomes a powerful tool in your quality assurance and asset reliability program.
