三棱钻杆/Triangle drill pipe
三棱钻杆是指煤矿巷道钻探用三棱锥型钻样，简收三楼钻杆、三角钻杆、防塌孔钻杆、防抱死钻杆: 是以带有锥型过渡的三棱圆弧钢管为钻杆杆体，与螺纹形式或三角、四方、六方等连接形式的钻杆接头，进行摩擦焊接制造而成的煤矿钻探用钻杆。三棱钻杆广泛应用于煤层及近煤层地质条件下的钻探、煤矿的探水和瓦斯排放的钻孔施工，也可用于物探和水利建设I程的锚固、钻探施工领域。
三棱钻杆系列产品是我公司近年来相继研发的具有自主知识产权的产品，分别获得多项专 利，分别是:一种煤矿巷道钻探用三棱锥型钻杆(ZL201120359764.1)、一种煤矿坑道钻探用三棱六方快接钻杆装置(ZL201320193491.7)、一种煤矿坑道钻探用推力排渣螺旋钻杆(ZL201320493681 0)。
Prismatc drill rod is refers to Coal Mine Roadway Dilling with triangular pyramid type drill pipe, reterred to as the three edged drill pipe.anti sloughing hole drill pipe, ABS pipe,is in a conical transition triangular arc steel for drill rod and thread form or trianguar,square hexagon connection form of dril pipe joints, friction welding made the coal mine diling dril. prismatic drill rod pipe is widely used in the coal seam and near coal seam geological conditions of drilling, coal mine water and gas drainage borehole construction,and can also be used in geophysical prospecting ane construction of water conservancy engineering anchor and drilling field.
prismatic drill rod series products is in recent years, our company have developed with independent intellectual property rights of patent product, won a number of national patents, respectively is: a triangular pyramid type drill pipe(ZL201120359764.1) Coal Mine Roadway Drilling, a coal mine tunnel drilling triangular hexagonal fast connecting rod device(ZL201320193491.7), a coal mine tunnel driling thrust slag spiral drill pipe(ZL201320493681.0).
