Special-shaped multi-edge grooved drill pipe is our company's invention patented product (patent number ZL 200910064973.0), referred to as heavy-duty three-edge grooved drill pipe. It is our company's newly developed coal mine tunnel drilling coal seam gas drainage drill pipe, which has a wide range of adaptability to coal seam hardness coefficient. It is widely used in deep hole drilling construction of high gas coal seam, especially soft coal seam. Under the reasonable design condition of bit diameter difference, the spiral groove thrust slag discharge structure is added on the basis of the triangular greasy smear mixing and protecting hole. Selection of high-quality joints and rod body material by friction welding, machining center CNC machine tool finishing, with high torque, adapt to the performance characteristics of high speed drilling.
