A geological drill pipe/fine buckle drill pipe is a drilling tool that is connected to a locking joint, transmits drilling torque to the bottom drill bit, and is responsible for transmitting drilling fluid. The material used for the rod body is Shanghai Baosteel STM-R780 (42MnMo7), which is not easy to fatigue bend or break, and has stable and reliable performance. The rod end is subjected to medium frequency heating, hydraulic upsetting and thickening, and 12 hours of buried tempering to ensure the density of the drill pipe and improve its mechanical properties. All adopt precision imported CNC lathes and customized forming cutters for thread processing, ensuring precision and tightness in connection with lock joints.
We can produce drill rods of different materials, lengths, diameters, and wall thicknesses, as well as customize drill rods according to customer requirements for materials, lengths, wall thicknesses, and threads.
