Auger Rod
1. The geological auger pipe is based on the high torque performance of the geological drill pipe. It adopts single helical blade or double helical structure blade, and is made by electric welding and welding through the coiling process of prestressed steel strand.
2. The drill pipe body is made of geological alloy pipe, and the drill pipe joint is made of alloy structural steel, which has been quenched and tempered in a vacuum environment to further improve the fatigue resistance li
