Quick-connect spiral drill pipe is a spiral drill pipe that can be quickly connected by spring pin automatic locking or semicircular pin, straight pin, U-shaped pin and long wedge pin for connection and positioning. The connection is convenient and quick, with the characteristics of light weight, high elasticity, and not easy to bend. Compared with other drill pipes, it has obvious advantages of convenient operation and fast drilling speed, so it is called quick connection spiral drill pipe. The quick-connection spiral drill pipe customarily refers to the four kinds of drill pipes of Φ42mm, Φ69mm, Φ76mm and 89mm. We designate them as all drill pipes of square or hexagonal quick-connection type, and also include other drill pipes of quick-connection type in a broad sense. Such as water exploration drill pipe, gas emission drill pipe, calibration drill pipe, rattan hemp drill pipe, large specifications coincide with geological spiral drill pipe.
