A combination of two non-destructive evaluation methods – magnetic flux leakage testing and visual inspection – magnetic particle inspection is used to check exposed pipe for surface anomalies. Magnetic particle inspection is part of an extensive suite of in-ditch pipeline inspection services used to assess pipeline condition, enabling owners and operators of pressurized piping systems to quickly and inexpensively identify defects.
Best used for: identification of stress corrosion cracking, hook cracks, and lack of fusion
- Combines non-destructive evaluation and visual inspection.
- Confirms surface-breaking defects.
- Performed on site by highly skilled technicians.
- What types of pipes or components can be inspected using magnetic particle inspection? The part being inspected must be made of a ferromagnetic material such as iron, nickel, cobalt, or some of their alloys.
- Will magnetic particle inspection work on pipe that is sweating? TDW offers fluorescent magnetic particle capabilities for a more sensitive inspection, or for when the pipe is sweating and testing cannot be accomplished with dry powder.
