On January 20, good news came from the Nantong Blue Sea New Materials project team: the manufacturing and installation of the instrument air storage tank for the air separation and air compression unit were successfully completed. The water filling and pressure testing were passed in one go, achieving excellent results with \"zero leaks and all parameters meeting the standards\" – thus laying a solid foundation for the safe and stable operation of the unit as well as for subsequent system debugging. It is reported that this instrument air storage tank is the core pressure vessel of the air separation compressors unit; it has a volume of 650 cubic meters, an inner diameter of 10.7 meters, a wall thickness of 42 millimeters, a height of 14.65 meters, and a net weight of 13.95 tons. It constitutes an important core component of the air separation compressors unit. This storage tank integrates multiple functions such as pressure stabilization, emergency backup, gas purification, and load regulation; it serves as a \"gas supply base\" to ensure the continuous and stable operation of the plant’s pneumatic instruments and automatic control systems. Its operational reliability is of great significance for the safe production of the plant. During the construction period, taking into account the large size of the equipment and the high precision requirements, the project team formulated a scientific construction plan and carried out the installation work in an orderly manner using the bulk installation method. From the construction of the foundation columns and the lifting and alignment of the spherical shell, to welding and shaping, overall heat treatment, and then to the preparations for water filling and pressure testing, each stage is closely linked and kept under control throughout the entire process. Technical personnel strictly adhere to the design requirements and construction specifications, focusing on enhancing control over weld quality and dimensional accuracy, thereby providing a solid technical foundation for ensuring the overall quality of the equipment.
