[Ten years of development of chemical equipment] 1050-2022 DN800 domestic largest diameter -196℃ ultra-low temperature ball valve
Thread Content
Chemical technology has developed greatly in the past ten years, praising China's prosperity and strength, and attracting attention. The sea is more lively and exciting with everyone's participation. Everyone is welcome to participate in more forum exchanges and discussions. July fires, pay attention to fire prevention------------------------------------------------- In November 2022, a batch of ultra-low temperature ball valves produced by Chengdu Chenggao for a domestic production capacity construction ground project successfully passed the factory acceptance and were shipped under the witness of the owner's representative. The diameter of the ultra-low temperature ball valve in this project ranges from DN50 to DN800 (the current largest diameter in China is -196°C ultra-low temperature ball valve), and the design minimum temperature is -196°C. The low-temperature test acceptance standard of the valve is in accordance with SHELL 77/200, and the leakage does not exceed 1/3 of the requirements of BS 6364.
Chengdu Chenggao has been committed to the research and development of ultra-low temperature valves since 2013. It has successively overcome the problems of material selection, structural design, batch processing of high-precision sealing surfaces, batch assembly of products, and batch testing of cryogenic ball valves, and has achieved localization and mass production of ultra-low temperature valve products. The ultra-low temperature valves produced by the company have been widely used in many projects in China, such as Kelameili Gas Field, Mahe Gas Field, Tarim Oil Field, and Beihai LNG, and the feedback has been good. Chengdu Chenggao will continue to innovate and make breakthroughs to meet the stringent requirements of customers in different industries for ultra-low temperature valves, promote the continuous advancement of domestic cryogenic valve technology, and make due contributions to the cryogenic valve industry!
