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.
