【Structural characteristics】
Triangle drill pipe, also known as triangular arc convex edge gas drainage drill pipe, abbreviated as triangular drill pipe, is divided into cone thread type, high-pressure thread sealing type, and triangular plug-in type according to the joint connection form. We mainly use high-quality medium carbon alloy steel pipes as the drill rod body, and the two end joints are made of high-quality 42CrMo material, which is formed by high-pressure treatment and vacuum quenching and tempering treatment. The process technology adopts internationally advanced interference welding assembly technology, avoiding quality hazards caused by the inability to use friction welding technology for welding. Compared with similar products, it greatly improves the mechanical performance of the product and the ability to adapt to complex geological conditions for deep hole drilling.
