On November 15, with the concerted efforts of our company for more than half a year, we finally successfully delivered Air Liquide French SHINE project, the largest liquid helium cold box product in China. This cold box product is designed and manufactured according to ASME, with a length of nearly 20m and up to now nearly 4m. The weight of a single cold box is about 80 tons. The quality requirements are very harsh, and the overall helium inspection is required to be qualified. Through our efforts, the product quality and progress have been highly recognized by Air Liquide French. The cold box is mainly used in Shanghai hard X-ray free electron laser device (shine), which is a major national science and technology infrastructure project with the largest investment and the longest construction cycle in China. This time, our company will provide three sets of large cold box products for this project.
