Answer: Main features: The quick-connect spiral drill pipe body is made of high-pressure seamless steel pipe, the drill pipe joint is made of 42CrMOA high-quality alloy structural steel through vacuum quenching and tempering treatment, and the drill pipe body is welded by advanced high-pressure interference assembly process and friction welding process. The spiral blade is made of high-wear T-shaped steel belt, which is welded by prestressed winding and full-automatic welding equipment. This series of products adopts four-way or six-way quick connection, which is automatically locked by spring pins when used, and is equipped with U-shaped or semi-circular anti-release pins to make the torque and drilling depth of the drill pipe reach the best state. Main process: quick-connect spiral drill pipe mainly adopts cold installation, hot installation, friction welding and other processes, in which cold installation process refers to the pre-processed inner square hole at both ends of the rod body, and then one end of the square steel is inserted into the pre-processed inner square hole to drill welding spot holes and pin holes for fixation, which is applicable to all quick-connect spiral drill pipes. hot installation process refers to the pre-processed inner square hole at one end of the rod body, at the other end, after the rod body is heated, the square steel is installed on the fixture, the square steel is directly pressed into the rod body, and then the hole is drilled and the pin is pressed and welded, which is suitable for F18, F24 and F32. The friction welding process can be applied to all quick-connect spiral drill pipes. At present, with the gradual improvement of the process, the friction welding process will gradually replace the existing cold and hot processes in the quick-connect spiral drill pipe, which greatly improves the comprehensive mechanical properties of the quick-connect spiral drill pipe.
