【Structure feature】
Geological drill pipe: the drill pipe body is made of high-quality Geological special alloy steel pipe, and the drill pipe joints are made of high-quality alloy structural steel. The fatigue strength and shear strength are greatly improved after the real air conditioning quality treatment.
Geological drill pipe adopts friction welding process to ensure the straightness requirement for deep hole drilling. The product has high fatigue resistance, long service life and strong welding.
SKU:FDG405
Geological drill pipeproduction equipment, fully USES the advanced CNC processing equipment, has the characteristics of high efficiency stable quality mainly adopts the high quality of carbon alloy steel pipe for drill pipe, rod body on both ends of the joint is made of high quality 42Crmo material, after high pressure processing forming, true air conditioning quality processing adopts the international advanced technology of interference welding assembly process, to avoid the caused by cannot use friction welding technology welding quality hidden trouble, compared with similar products has greatly increased the mechanical properties of the product and the ability to adapt to the complicated Geological conditions of deep hole drilling.
