High-quality geological drilling special alloy steel tube is used for the drill rod, drill pipe joints using high quality alloy structural steel, by high pressure molding, vacuum quenching and tempering treatment, friction welding, advanced production technology and processing； rib pipe in soft coal seam and the rockburst conditions greatly reduces the drill rod locking, drill damaged and lost phenomenon. In addition, because of the wide helical blade of the rib. the rib drill rod can not be cut in the drilling hole wall, and will not cause the deviation of the hole wall. Groove drill pipe, also known as rib pipe body is in high-quality thick alloy steel based, using advanced CNC machining process for tube body slot milling, relative to the rib rod, groove drill pipe have rib pipe discharging speed, small rotational drag advantage, also in the deep hole drilling, due to the advantages of integrated design process and the wall thickness, the better wear resistance using longer life.
