Effect of Magnetic Field on Corrosion Behavior of X52 Pipeline Steel in Simulated Soil Solution

International Journal of Electrochemical Science, 2021
Magnetic flux leakage detection is the primary method used for detecting metal damage in oil and gas pipelines. After a magnetic flux leakage test is used, a residual magnetic field remains in the steel pipeline for a long time.

The physical properties of magnetic inks [PDF]

, 1988
The magnetic particle inspection (MPI) method is a widely used non destructive testing (NDT) technique for ferrous structures. Magnetic inks used in MPI are suspensions of fine ferro/ferrimagnetic particles which, when applied to a magnetized test ...

Miniature mobile sensor platforms for condition monitoring of structures

, 2009
In this paper, a wireless, multisensor inspection system for nondestructive evaluation (NDE) of materials is described. The sensor configuration enables two inspection modes-magnetic (flux leakage and eddy current) and noncontact ultrasound.
