As a common non-destructive testing method, steel pipe magnetic flux leakage testing has formed a complete set of industry standards and specifications.
Leakage magnetic field detection refers to the formation of a leakage magnetic field on the surface or near surface of a ferromagnetic material due to defects after magnetization.
Magnetic Flux Leakage Testing does not require preprocessing of the test object, is easy to obtain detection signals, has a high degree of automation, and can detect different types of defects.
Magnetic particle testing is called "magnetic flux leakage testing" because this technology is based on the leakage of magnetic flux on the surface or near the surface of the material.
