Forging joint: the joint material is forged to improve the density of the material, change the fiber structure of the material, so as to improve its comprehensive mechanical properties; Rod body conditioning and tempering: drill pipe body after conditioning and tempering treatment, to meet the requirements of high elasticity, high strength and high toughness of drill pipe for guiding drilling; Optimized design: drill pipe through the same strength and stress dispersion optimization design, can give full play to the potential of drill pipe materials; When the male and female joints of the double top structure are tightened, the inner and outer shoulders are tightened at the same time, so that the drill pipe can bear greater torque and bending force. Nitriding treatment: nitriding treatment of the joint wire buckle parts, improve the surface abrasion, and prevent adhesion; The end of the tube body was upset to ensure that the friction welds would not break.
The DTH drill pipes produced by our company are all processed from materials produced by well-known large iron and steel enterprises in China (Shanghai Baosteel, Hunan Henggang, Xining Special Steel, etc.) All use professional CNC machining, all threads are equipped with thread gauges that conform to international standards, the pipe end of the rod body adopts the internal thickening process, and is tempered after friction welding, so the quality of the processed drill pipe is stable and reliable. The cycle is greatly extended.
