Magnetic Particle Testing (MT)
Magnetic Particle Testing (MT) is a non-destructive testing that utilizes the fact that after ferromagnetic materials are magnetized, a leakage magnetic field is generated at surface or near-surface defects, which attracts magnetic particles (fluorescent or non-fluorescent) to form visible magnetic traces for locating defects.

Application Range

Key components of drilling and production equipment, such as drill pipe/drill collar threads, downhole tools, and sucker rods
Welds of pressure vessels and pipelines
Flange sealing surfaces
Valves and pressure-bearing components, such as wellhead valve bodies and manifold elbows
Offshore platform structures

Technical Features

  • Magnetic Particle Testing is the "gold standard" for surface crack screening in the oil and gas industry. With its advantages of being intuitive, fast, and low-cost, it is irreplaceable in ensuring the safety of drilling tools, conducting weld quality inspections, and maintaining offshore platforms.
