Features and advantages： 1. The standard drill pipe is mechanically locked. Each section of the drill pipe can be locked with each other. The first section of the drill pipe can be locked with the power head. 2. The lower end of the drill pipe is equipped with a spring or rubber shock absorption system to absorb the impact caused by the drill pipe lifting or the drill pipe hitting the rod. 3. The upper part of the middle section of the drill pipe is equipped with a high-strength and wear-resistant movable ring, which plays a guiding role during the lifting and lowering of the drill pipe and ensures the uniform wear of the driving key plate in the drill pipe. 4. The lower end of the drill pipe is welded with an integral high-strength wear-resistant ring, which is conducive to the uniform wear of the drill pipe driving key and the pressure key, and is conducive to the deformation of the driving sleeve in the drill pipe.
We have established a vast network of end-users across China and developed a highly mature procurement channel for used machinery.
