Thread Content

Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Continuous updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** China’s first high-temperature floating ball valve hot oil testing platform has been put into operation. This platform, with a design temperature of 450°C and a pressure of 60 MPa, fills a gap in domestic technology, helps advance the localization of high-end ball valves, and contributes to ensuring energy security. Recently, Beijing Aerospace Changzheng Machinery Equipment Manufacturing Co., Ltd., which is part of China Academy of Launch Vehicle Technology’s Aerospace Changzheng Chemical Engineering Co., Ltd. (referred to as “Changzheng Machinery”), completed China’s first hot oil testing platform for high-temperature floating ball valves, marking a significant technical breakthrough in the field of high-temperature and high-pressure ball valves in China. The design temperature of this testing platform is up to 450°C, and its design pressure is up to 60 MPa; it has the capability to simulate extreme field conditions, filling a technical gap in this field in China. This achievement relies on the design and general contracting capabilities of Aerospace Changzheng Chemical Engineering Co., Ltd., and integrates a number of independently developed innovative technologies. The testing platform is capable of accurately simulating extreme conditions under actual operating conditions; it also provides reliable testing methods and data support for the development of high-temperature and high-pressure ball valves as well as other key pipe and valve components. It holds significant strategic importance for ensuring **energy security**. Based on this testing platform, Hangzheng Machinery has successfully designed and developed a variety of high-temperature and high-pressure floating ball valves for its customers. This has enabled these valves to incorporate numerous original technologies, improving their sealing performance and operational efficiency, and ensuring their stable operation under harsh working conditions. This series of innovative designs reflects the significant progress made by Hangzheng Machinery in the design and manufacturing of high-temperature and high-pressure floating ball valves, laying a solid foundation for China’s technological advancement in this field. High-temperature and high-pressure floating ball valves are key equipment widely used in industries such as petrochemicals, coal-to-oil conversion, and oil refining; they play a crucial role especially in residue hydrogenation and direct coal liquefaction plants. For a long time, high-end products in this field have relied heavily on imports, with significant technical barriers. The successful operation of this testing platform demonstrates that Hangzheng Machinery has made a significant breakthrough in the localization of high-temperature and high-pressure floating ball valves, thereby greatly enhancing the technical level and competitiveness of the industry. In the future, Hangzheng Machinery will continue to be guided by market demands, increase investment in research and development, and constantly optimize and improve the design and manufacturing technologies for high-temperature and high-pressure floating ball valves. It will promote the widespread use of such valves in fields such as aerospace, nuclear power, and deep-sea exploration, helping to elevate China’s technology in this area to a higher level. This will provide a stronger foundation for achieving technological self-reliance and strength, as well as contributing to the development of China’s high-end equipment manufacturing industry.
