产品详细说明

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,经预应力缠绕工艺加工焊接而成。
钻杆杆体选用*地质*合金钢管,钻杆接头选用*合金结构钢,经真空调质处理,大大提高了抗疲劳强度和抗剪切强度。
采用*的摩擦焊焊接生产工艺,钻杆具有抗弯强度高,焊接牢固等特点。
生产设备完全采用*的数控加工设备,具有生产*、质量稳定的特点。能够保证深孔钻进时对直线度的要求。超低螺旋的螺旋叶片设计使该产品具有扭矩大,排渣速度快,钻孔成型好,不易卡钻的特点。特别适合于通水排渣效果不好的松软煤层和类煤岩的深孔钻探。
直径Φ73以下的地质螺旋钻杆,可与各种全液压钻机直接配套使用,利用钻机直接夹装钻杆螺旋外圆进行钻进和更换钻杆,方便快捷,大大降低了操作人员的劳动强度。在超松软高压煤层条件下的钻孔,采用套钻施工工艺时,可选用直径为90,113,133,146的大螺旋地质钻杆,便捷实现岩芯管的铺设安装。本系列产品为矿井的*深孔钻探提供了保证,填补了国内空白。
