Triangular drill pipe can be stably drilled in soft and outburst coal seam, reducing the in-hole accidents such as holding drill and drill pipe fracture that often occur when using ordinary drill pipe. Through the design and improvement of the structure and parameters of triangular drill pipe, the process flow, welding process and heat treatment process of triangular drill pipe are analyzed and optimized.
triangular drill pipeThe ability to drill stably in soft outburst coal seams and reduce in-hole accidents such as holding and drill pipe breakage that often occur when using ordinary drill pipes.triangular drill pipeThe structure and parameters are designed and improved, the process flow, welding process and heat treatment process of triangular drill pipe are analyzed and optimized, the joint is connected by friction, the quality of the traditional electric welding seam is improved, and the problem of fracture at the weld is solved.
Triangular drill pipe is designed to be used in ZDY1250S, ZDY1900S, ZDY3200S and ZDY4000S drilling rigs. The main technical parameters of ZDY4000S drilling rig (maximum output torque) are: output torque 1050-4000Nm, output speed 50-240 r/min
Triangular drill pipe shall meet the following two conditions:
① The drill pipe can effectively mix the cinder at the bottom of the hole during drilling;
② The drill pipe can bear the torque on the matching drilling rig.
Key words:
Yi Kuang Science and Technology Three-pronged drill pipe
