35CrMo or 42CrMo materials are selected, strictly controlled heat treatment process and standard API thread processing technology are adopted, quenching and tempering heat treatment is conducted after rough machining, and surface nitriding treatment is conducted after finish machining, which is more wear-resistant and easy to disassemble, effectively eliminating failure probability such as gluing, breaking, and outer diameter cracking. All use precision imported CNC lathes and customized forming knives for thread processing, which can ensure the tightness of the threads of the drill pipe joints and achieve consistent precision and interchangeability of the drill pipe joints.Tool Joint For Drill Pipe
