地質螺旋鉆桿/ Spiral geological drill pipe

       地質螺旋鉆桿是我公司在地質鉆桿高扭矩性能的基礎上,采用單螺旋葉片或雙螺旋葉片,經預應力纏繞,全自動焊接而成。鉆桿杄體采用高等級地質鉆探專用合金鋼管,鉆杄接頭選用優質合金結構鋼,經高壓成型、真空調質處理,經摩擦焊接精工制造而成,具有抗彎強度高、焊接牢固、排渣效率高的特點。與同類產品相比,大大提高了抗疲勞強度和抗剪切強度。地質螺旋鉆杄主要適用于中硬以上地質條件的深孔鉆探施工,大大提高了鉆探施工的生產效率,是煤礦高效鉆探施工、節能降耗的產品。
       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 .
