Taper Thread Spiral drill rod is a high  torque performance of the drill pipe, the use of single screw blades or double  helical blade, the prestressing force is wound, the whole automatic welding. High grade geological drilling special alloy steel tube is used for the drill  rod, drill pipe joint selection of high quality alloy structural steel, the  high-pressure molding, vacuum quenching and tempering treatment, the friction  welding precision manufacturing and and has characteristics of high bending  strength, welding firm, deslagging efficiency high. Compared with similar  products, the anti fatigue strength and shear strength are greatly improved.  Geological spiral drill pipe is mainly suitable for medium hard and above  geological conditions of deep hole drilling construction, greatly improving the  production efficiency of drilling, is the first choice for high efficiency drilling  construction, energy saving and consumption reduction.
