It adopts the patented thread structure, which reduces the stress by more than 50% compared with the common API thread, effectively overcomes the early fatigue fracture easily generated by the original thread structure drill pipe, and can fully exert the torque and tension of the drilling machine, especially in the hard rock excavation. increase work productivity.

The drill pipe adopts equal strength design, which reduces the overall weight of the drill pipe and effectively improves the drilling depth and the fatigue resistance of the drill pipe.
