The rod body material is made of Shanghai Baosteel STM-R780 (42MnMo7), which is not easy to fatigue bend or break, and the performance is stable and reliable. The rod end is heated by medium frequency, the hydraulic upsetting is thickened, and the buried tempering is carried out for 12 hours to ensure the density of the drill pipe and improve the mechanical properties. All adopt precision imported CNC lathe, custom forming for thread processing, precision and ensure the tightness of the connection with the lock joint.
