地質(zhì)螺旋鉆桿/ Spiral geological drill pipe
地質(zhì)螺旋鉆桿是我公司在地質(zhì)鉆桿高扭矩性能的基礎(chǔ)上，采用單螺旋葉片或雙螺旋葉片，經(jīng)預(yù)應(yīng)力纏繞，全自動(dòng)焊接而成。鉆桿杄體采用高等級(jí)地質(zhì)鉆探合金鋼管，鉆杄接頭選用合金結(jié)構(gòu)鋼，經(jīng)高壓成型、真空調(diào)質(zhì)處理，經(jīng)摩擦焊接精工制造而成，具有抗彎強(qiáng)度高、焊接牢固、排渣效率高的特點(diǎn)。與同類(lèi)產(chǎn)品相比，大大提高了抗疲勞強(qiáng)度和抗剪切強(qiáng)度。地質(zhì)螺旋鉆杄主要適用于中硬以上地質(zhì)條件的深孔鉆探施工，大大提高了鉆探施工的生產(chǎn)效率，是煤礦鉆探施工、節(jié)能降耗的產(chǎn)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 .
