On November 30, at the demonstration project site of 300MW compressed air energy storage power station in Yingcheng, Hubei Province, the Φ339.72*12.19mmN80Q corrosion resistant bimetal composite oil casing produced by Jingjiang Special Steel Co., LTD., a subsidiary of CITIC Pacific Special Steel Group, was successfully used in the injection and production string of the first well of the project. The pipe string passed the inspection successfully, and all parameters were qualified and applied in well.
At the project site, Liu Wenxue, general manager of Jingjiang Special Steel, said that Jingjiang Special Steel has been committed to improving the strength of scientific and technological innovation, and this is the first time in China to successfully apply laser cladding corrosion resistant alloy technology to the field of energy pipes, opening up a new track of low-cost, high-corrosion resistance composite pipe manufacturing technology. The successful application of this technology can greatly reduce the cost of pipe under harsh corrosion conditions.
In March this year, after receiving the project information, the research institute of CITIC Pacific Special Steel Pipe Division and the sales company quickly organized the establishment of a project research team. According to the scheme of compressed air energy storage using salt brine cavity proposed by the design institute, through repeated demonstration and trial production test, the technical scheme of replacing nickel-based alloy pipes with corrosion-resistant bimetal composite pipes was proposed. While meeting the design requirements, To achieve the best cost performance. This scheme has been unanimously recognized by the design institute, the owner and the engineering side, and Jingjiang Special Steel has successfully obtained all the pipe supply qualifications of the project.
In the future, Jingjiang Special Steel will continue to improve its research and development strength, manufacturing level and technical service capabilities, and is committed to providing users with one-stop comprehensive solutions for customized products, providing strong technical support for tube selection, research and development, production, use and service under harsh conditions, and contributing to the construction of national key projects.
