三棱鉆桿/Triangle drill pipe
三棱鉆桿是指煤礦巷道鉆探用三棱錐型鉆樣，簡收三樓鉆桿、三角鉆桿、防塌孔鉆桿、防抱死鉆桿: 是以帶有錐型過渡的三棱圓弧鋼管為鉆桿桿體，與螺紋形式或三角、四方、六方等連接形式的鉆桿接頭，進行摩擦焊接制造而成的煤礦鉆探用鉆桿。三棱鉆桿廣泛應用于煤層及近煤層地質條件下的鉆探、煤礦的探水和瓦斯排放的鉆孔施工，也可用于物探和水利建設I程的錨固、鉆探施工領域。
三棱鉆桿系列產品是我公司近年來相繼研發的具有自主知識產權的產品，分別獲得多項專 利，分別是:一種煤礦巷道鉆探用三棱錐型鉆桿(ZL201120359764.1)、一種煤礦坑道鉆探用三棱六方快接鉆桿裝置(ZL201320193491.7)、一種煤礦坑道鉆探用推力排渣螺旋鉆桿(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).
