Experimental Manufacture of Hi-grade Steel Tube for Perforating Gun-making

The subjective hi-grade steel tube is used for making the key component of the hi-efficiency perforating gun as used for oil/gas well service. Such material was in the past totally imported from abroad. Based on the research involving steel grade design, property design and ID control technology of the said tube, a control technology focusing on ID to manufacture the tube is developed, resulting in development of the said tube with all the target property values satisfactory to customer requirements.
