The non-magnetic weighted drill rod is made of N1310 low-carbon alloy steel, which is forged through strict chemical composition analysis. The material has undergone mechanical performance testing to ensure that its hardness, toughness, impact value, and corrosion resistance meet the standards, and it has good low magnetic permeability and good mechanical processing performance.

Non magnetic weighted drill pipe is a drill pipe that has a certain strength, stiffness, low permeability, and is never magnetized. The main characteristics include higher strength (about twice that of stainless steel), replacing traditional stainless steel products, better performance of non-magnetic weighted drill pipes, lighter weight (about half that of stainless steel), and reduced operational difficulty; The most important feature is non-magnetic, completely replacing the disadvantage of stainless steel having micro magnetism. Mainly used in geological exploration teams, road construction, petroleum instrument production, logging instrument measurement and control instrument production, and so on.

Parameters of non-magnetic weighted drill rods
