Drilling tool pipe joint nitriding+post oxidation heat treatment

Each component of the drilling tool is made of high-quality seamless steel pipe, which has excellent physical and mechanical properties to withstand the alternating load, fatigue and wear of the drilling tool itself during the drilling process. The deeper the hole is drilled, the higher the performance requirements of drilling tools are. The drilling tools will be scrapped due to wear and corrosion after a certain working period. In order to improve the wear resistance of the surface of the drilling tool, nitriding+oxidation is carried out on the surface of the drill pipe, especially the joint and its thread, which can greatly extend the service life of the drill pipe.
