Product Performance Overview
Special-shaped multi-edge grooved thrust slag discharge drill pipe, referred to as heavy triangular grooved drill pipe, is the latest research and development of our company coal mine tunnel drilling this coal seam gas drainage drill pipe, the coal seam hardness coefficient of the adaptability of the new drilling tool products. It is an invention patent of our company (Invention patent number:ZL200910064973.0）It is widely used in deep hole drilling construction of high gas coal seam, especially soft coal seam. Production is separatelyExternal triangular transmission type grooved drill pipe, hexagonal double pin quick connection tensile type grooved drill pipe, large hole threaded connection type grooved drill pipe, hexagonal double pin quick connection tensile type geological spiral drill pipe and other series products. Among them, the hexagonal double-pin quick-connect tensile type can perform the reverse function of the drilling tool and can withstand it.Drawing force of 350kN. Under the design condition of reasonable bit diameter difference (10-15mm), the spiral groove thrust slag discharge structure is added on the basis of the triangular greasy smear stirring protection hole. Selection of high-quality joints and rod body materials by friction welding, machining center CNC machine tool finishing, with high torque, high wear resistance, to adapt to high speed drilling performance characteristics.
Key words:
Triangular drill pipe, drill pipe, spiral drill pipe, new coal drill pipe, rib drill pipe
