Magnetic Particle Inspection (MPI)

Magnetic Particle Inspection (MPI)

This method works on the material surface using a magnetic flux, magnetic ink and a background contrast colour. This can be used to detect surface breaking and near surface discontinuities that can be problematic to the function and life of the material under test.

MPI on welds on pipelines, structures, storage tanks and pressure vessels fabricated from Ferro-magnetic materials e.g. carbon steel, to the client’s specifications, international standards and acceptance criteria.

This method can be fixed via a bench unit or mobile, using a powered or permanent magnet, using solvent based consumables for general use and water based consumables thus enabling its use in confined spaces such as pressure vessels.
