BGJT Special Steel Group's first batch of 450 tons of E4340 steel for oil and gas drilling, production and blowout prevention pipes that met international advanced technology standards has been successfully delivered to customers. After being processed by users, this product will help the development of national new energy shale gas, and it can also be used to replace imports and high-end exports, with higher profits and a broad market.
In recent years, with the continuous advancement of China's ecological civilization, new energy represented by clean energy shale gas has become a strategic emerging industry in China to accelerate its cultivation and development. Since the beginning of this year, according to customer needs, BGJT specializes in the application of new energy shale gas special steel, and has successfully developed the E4340 oil and gas drilling and production blowout prevention pipe steel that meets international advanced technology standards and is successfully delivered.
"Oil and gas drilling and blowout preventive pipes are important structural pipe fittings to prevent blowouts in oilfield blowout accidents. Because they are used in the special environment of high acid gas oil and gas fields, they must have high strength, low temperature impact toughness, and pure steel Degree, as well as excellent corrosion resistance and wear resistance. "Lu Bingjun, chief engineer of the Special Steel Research Institute of BGJT Plate Technology Research Institute, introduced.
The steel grade has always depended on imports, and the difficulty of research and development has mainly focused on the absorption and promotion of relevant standards and technological transformation. For this reason, BGJT conducted a large number of laboratory data simulations during the research and development process, which minimized the probability of abnormal problems in the production process. This steel type adopts the converter continuous casting rectangular billet + special steel bar continuous rolling process path. The first batch of trial production of BGJT's oil and gas drilling and blowout prevention pipe steel E4340 adopts ASTM (American Materials Testing Association) standards, and absorbs and promotes the application ASTM inspection standards.
In order to ensure a successful trial production, the technicians of the BGJT Plate Technology Research Institute worked with production technical personnel of the Benxi Iron and Steel Plate Smelting Plant, the Plate Special Steel Plant, and the Plate Inspection and Testing Center to analyze the technical difficulties, study process measures, and formulate the process The emergency plan is controlled and the whole process is tracked and monitored to ensure that the process goes forward. Through comprehensive testing and analysis, the technical indicators of the products developed this time have reached the international advanced level.
