Magnetic Particle Inspection (MPI)

Magnetic Particle Inspection (MPI) is a method primarily used for detecting surface breaking discontinuities in ferromagnetic materials. It works by magnetising the component and then applying ferrous particles in the form of an ink to the item, with any surface breaking discontuities being shown by the collection of the particles

PTS provides a range of different Magnetic Particle Inspection options for testing all types of components. From small items such as castings and forgings in our laboratory using our tailor made bench unit using fluorescent MPI, to inspection on in-service components at any location nationwide using the colour contrast method and portable equipment. We can cater to any of your requirements. We have engineers qualified to PCN level II and III, each having a vast knowledge of various specifications and standards.

Magnetic Particle Inspection can be carried out either in a workshop, on in service items at sites around the country or at our purpose built laboratory in the Midlands.
