地质螺旋钻杆/ Spiral geological drill pipe
地质螺旋钻杆是我公司在地质钻杆高扭矩性能的基础上，采用单螺旋叶片或双螺旋叶片，经预应力缠绕，全自动焊接而成。钻杆杄体采用高等级地质钻探合金钢管，钻杄接头选用合金结构钢，经高压成型、真空调质处理，经摩擦焊接精工制造而成，具有抗弯强度高、焊接牢固、排渣效率高的特点。与同类产品相比，大大提高了抗疲劳强度和抗剪切强度。地质螺旋钻杄主要适用于中硬以上地质条件的深孔钻探施工，大大提高了钻探施工的生产效率，是煤矿钻探施工、节能降耗的产品。
The geological spiral drill pipe 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 .
