The drill pipe joint and the drill pipe body of the integral drill pipe are directly connected by male and female buckles. The thickening structure of the drill pipe body, the outer wall and inner wall of the drill pipe joint are all integral thickening structures. The processing technology is that the male buckle end is firstly heated by intermediate frequency twice, forged and thickened, polished, then heated by intermediate frequency twice, and the cake is thickened.; Turn the workpiece around, the female buckle end is heated in intermediate frequency twice, to be thickened, polished, then heated in intermediate frequency, the iron is thick, and the thread is processed after grinding.
The drill pipe and the joint do not need friction welding, nor do they need to carry out subsequent welding related treatment, thus simplifying the processing technology and reducing the cost of processing equipment. The drill pipe joint and the drill pipe body of the integral drill pipe are directly connected by male and female punching to ensure the air tightness and strength of the connection. At the same time, the outer diameter of the drill pipe joint is correspondingly reduced and the performance of the drill pipe is improved. Good product quality, long service life, safe and reliable.
