Non-magnetic steel components play a critical role in mine-use kilometer directional drilling systems, where accurate downhole measurement is essential. These components—such as non-magnetic drill pipes, stabilizers, and screw motors—are made from high-performance austenitic alloys that exhibit extremely low magnetic permeability, effectively shielding magnetic interference between the drill string and sensitive measurement-while-drilling (MWD) probes.

In kilometer drilling operations, especially in complex coal seams, ferromagnetic materials can distort the Earth’s magnetic field, leading to inaccurate azimuth and tool face data. By integrating non-magnetic steel sections near the bottom hole assembly (BHA), drilling systems ensure reliable transmission of real-time geological data, enabling precise trajectory control.

JMAG’s non-magnetic components are forged from premium materials (e.g., 18Cr-8Ni-based alloys), offering high strength, corrosion resistance, and durability in harsh underground environments. They are widely used in gas drainage, water detection, and long-hole drilling applications, supporting the intelligent and efficient development of modern coal mines.
