The distillation tower delivered this time has a diameter of 5.4 meters, a length of 70.65 meters, and a total weight of 333 tons; it is the largest tower ever manufactured by Jinhua Machinery. During the manufacturing process, constructing such large-diameter towers requires a high level of precision; accuracy is needed in terms of straightness, the ellipticity of the cylinder, as well as the gaps between the internal components. There are over 1,000 internal components in the tower, along with 76 layers of trays inside it, making the overall workload extremely large. Prepare thoroughly. The Group’s Production Management Department held numerous engineering review meetings and technical exchange sessions to discuss the product specifications. Various functional departments worked closely together, engaging in ongoing communication to ensure all necessary elements were in place. The challenges related to equipment manufacturing, construction methods, technical requirements, quality standards, and safety measures were identified, thereby providing a solid foundation for the smooth delivery of the equipment. At the same time, by drawing on past manufacturing experience, production plans are formulated scientifically and resources are allocated carefully to ensure that the key points in various stages of the production process are effectively controlled. Strict manufacturing. The mixing workshop, high-pressure vessel workshop, material preparation workshop, and metalworking workshop strictly follow the process standards throughout the entire production process. The challenging processes such as the rolling and forming of large-diameter composite plate cylinders, alignment, welding, and the installation of internal components were carried out step by step. The ellipticity, straightness, and verticality of the cylinders were tightly controlled to keep the equipment’s precision errors within acceptable limits; all technical specifications were met, allowing the segmented manufacturing tasks within the factory to be completed successfully.
