       Based on the geological drill pipe, the rib drill pipe is made of high abrasion resistant plane helical blade, and is welded with the fully automatic welding. High-quality geological drilling special alloy steeltube is used for the drill rod, drill pipe joints using high quality alloy structural steel, by high pressuremolding, vacuum quenching and tempering treatment, friction welding, advanced production technologytand processing; rib pipe in soft coal seam and the rockburst conditions greatlyreduces the drillrod lockingdrill  damaged and lost phenomenon. In addition, because of the wide helical blade of the rib, the rib drill rodcan 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 machiningprocess for tube body slot milling, relative to the rib rod, groove drill pipe have rib pipe discharging speedsmall rotational drag advantage, also in the deep hole drilling, due to the advantages of integrated designprocess and the wall thickness, the better wear resistance using longer life.
