Spiral geological drill rod Φ194 (561)

The spiral geological drill pipe is produced on the basis of high torque performance of geological drill pipe, using single screw blades or double helical blade, by the craft of prestressed winding welding. High grade geological drilling special alloy steel tube is used for the drill rod and pipe joint selects high quality alloy structural steel, molded under high-pressure, with quenching and tempering treatment in vacuum. The friction welding ensures characteristics of high bending strength, firmness, high efficiency deslagging . Compared with similar products, the fatigue strength and shear strength are greatly improved. Geological spiral drill pipe is mainly suitable for deep hole drilling under medium hard and above geological conditions construction, greatly improving the production efficiency of drilling, is the first choice for high efficiency drilling construction, energy saving and consumption reduction.
