What Is Magnetic Particle Testing (MPT)? Magnetic Particle Testing (MPT) is a highly effective non-destructive testing (NDT) method that one uses to identify surface and near-surface flaws in ferromagnetic materials, such as carbon steel and iron alloys. MPT applies a magnetic field to the material. Magnetic particles then accumulate around imperfections, revealing discontinuities that… Continue reading Magnetic Testing Pressure Vessels: Ensuring Structural Integrity
