Fine-thread drill pipe/Geological Drill pipe/Water well drill pipe
This kind of pipe is used for geological prospecting, water well drilling, eothermal well drilling project, etc.
The fine-thread drill pipe is a drilling tool that is connected to the lock joint to transmit the torque of the drill to the bottom hole and to transport the drilling fluid. The rod material is selected from Shanghai Baosteel STM-R780 (42MnMo7), which is not easy to be bent or broken, and the performance is stable and reliable. The rod end is heated by medium frequency, hydraulically thickened and thickened, and 12 hours of buried tempering ensures the compactness of the drill pipe and improves the mechanical performance. All of them are made of precision imported CNC lathes, and the custom-made knives are threaded, which ensures the tightness of the connection with the lock joint.
