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.
