The non-magnetic drill pipe for mining is made of non-magnetic steel from a reputable Chinese steel plant, after strengthened treatment and reformed forging. It is widely used in major coal industry and scientific research institutes. In recent years, it has replaced beryllium copper in directional drilling and coal bed methane extraction applications.
Application
This product is widely adopted in coal mine directional drilling, coalbed methane (CBM) extraction, and geological survey drilling. In recent years it has largely replaced beryllium copper drill pipe in these applications, offering superior safety characteristics alongside equivalent non-magnetic performance. Its combination of low density, low elastic modulus, and high strength-to-mass ratio makes it particularly suitable for shallow to medium-depth directional drilling where precise survey readings are essential and tool weight management is a priority.
