A leading company in Magnetic Particle Inspection

Magnetic Particle Inspection (MPI) is a very popular Non-Destructive Testing process for detecting surface or sub-surface (up to 3mm deep) discontinuities in ferromagnetic materials.

MPI is used to inspect a variety of product forms including castings, forgings, and weldments. A relatively quick and cost effective method of inspection, it can be conducted by one operative with lightweight equipment in most environments.

IACS use PCN level 2 qualified personnel to undertake Magnetic Particle Inspection, with a high level of expertise built over many years providing this service to a wide range of clients worldwide.

Examples of industries which can benefit from using MPI to determine component fitness include structural steel, automotive, petrochemical, power generation, and aerospace industries. MPI is also used in underwater testing and inspection of items such as structures and submerged pipelines.

Advantages of IACS Magnetic Particle Inspection include:

  • Rapid inspection of large and small areas onsite or in the workshop
  • Effective  detecting including underwater structures, complex components and irregular shapes (external splines, crankshafts, connecting rods)
  • Immediate indication of surface and subsurface flaws directly on specimen surface
  • Surface preparation less critical than in penetrant inspection
  • Safe, quick, uncomplicated, and inexpensive compared to radiography
  • Elaborate pre-cleaning not required
  • Inspection units can be extremely portable and low cost
