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】Regular updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Major breakthroughs have been achieved in China’s ultra-low temperature equipment; the country’s first 120-cubic-meter fixed ultra-low temperature storage tank has been developed. On July 18th, a presentation on the technical achievements related to this 120-cubic-meter fixed ultra-low temperature storage tank was held at the Equipment Manufacturing Branch of CPECC’s Seventh Construction Company, marking a significant breakthrough in China’s ultra-low temperature equipment sector. Previously, at the 12th World Congress on Chemical Engineering and the 21st Asia-Pacific Chemical Industry Association Conference, this technology was recognized as an outstanding technical achievement at the \"2025 International Chemical Innovation Exhibition New Products and Technologies Presentation.\" The successful development of the 120-cubic-meter fixed ultra-low temperature storage tank has enabled full autonomy and control over key materials, core manufacturing processes, and the overall production of the unit; its static evaporation rate is less than 0.49%/day, which is at the international advanced level. Compared to existing small containers in the domestic market, the loading time for this storage tank has been reduced from 7 days to 8 hours, while the gasification rate during the loading process has dropped from 50% to 3%. To date, CPECC has filed a total of 18 invention patents related to this technology, and has taken the lead in formulating 9 industry and group standards. Furthermore, this product has obtained the PED certification from Bureau Veritas in France. Over a period of 3 years, CPECC overcame challenges such as the limited availability of physical property data for ultra-low temperature materials and the difficulty of evacuating air from insulating materials, thereby ensuring the gas-tightness, reliability, stability, as well as the crack resistance and insulation properties of the storage tanks under extreme temperature differences. On March 17 this year, the tank was tested at the project site. Its technology can be applied in fields such as cryogenic liquids like liquid hydrogen, and it can also support cryostats for controlled nuclear fusion and cryogenic plants, offering broad application prospects. Yuan Shiyi, an academician of the Chinese Academy of Engineering, said that the release of this \"major national asset\" is inspiring; the next step is to comprehensively improve the software, hardware, as well as theoretical and technical aspects, in order to establish China’s first industrial chain for ultra-low temperature storage tanks and achieve industrialization.
