This is just a starting point; more participation from everyone will make things even more lively. The forum becomes better with your presence; we welcome everyone to engage more in discussions here. The fragrance of rice in August ------------------------------------------ On July 20, 2023, the 120-cubic-meter multi-layer insulated ultra-low temperature storage tank developed and manufactured by CPECC, a subsidiary of CNPC Engineering, passed expert testing. Its storage capacity is 12 times that of the existing 10-cubic-meter tanks in China, indicating that CPECC has reached a leading level in the field of designing and constructing large-capacity ultra-low temperature storage tanks in China. Ultra-low temperature storage tanks are one of the key devices in fields such as the comprehensive utilization of natural gas, hydrogen energy, and new energy technologies like CCS/CCUS. They play an important role in ensuring the stable operation of the overall process in liquefied gas plants, enhancing the storage capacity of these plants, reducing the time required for transporting ultra-low temperature substances, and minimizing product losses and energy consumption. Therefore, large-capacity ultra-low temperature storage tanks have become essential equipment standard in large-scale ultra-low temperature liquefied gas plants, distribution centers, and storage facilities. The design and manufacture of large-capacity ultra-low temperature storage tanks present a series of technical challenges, including large span between tank sections, significant deformation due to temperature differences, complex support structures, difficulties in optimizing insulation, a shortage of domestically produced ultra-low temperature valves, stringent requirements for welding quality at ultra-low temperatures, high precision demands for fitting, and long vacuum pumping times. China lacks experience in the design and manufacture of large-scale ultra-low temperature storage tanks, which severely hinders the development of related industries. To address the technical challenges related to storage and transportation in the ultra-low temperature industry chain, the group company established special scientific and technological projects. CPECC actively participated in the research and development of related technologies, with its New Energy Division taking the lead in forming a research team focused on the development of large-capacity ultra-low temperature storage tanks at near-absolute zero temperatures. CPECC North China Branch and CPECC’s Seventh Construction Company established research institutions such as ultra-low temperature research centers and storage and transportation technology institutes. The equipment manufacturing branch of the Seventh Construction Company built a specialized ultra-low temperature equipment manufacturing facility for the development of this product.
