On December 31, 2025, with the structural inspections of the last batch of units in the Inner Mongolia Rongxin Polypropylene project operated by the fourth branch – including the pellet mixing unit, buffer silos, steam drying system, tubular reactor, and flare system – completed, the structural inspection process for the ten core units of this project was fully brought to an end. The achievement of this key milestone marks the official transition of the project from the civil construction phase to the critical stages of equipment installation and process debugging, laying an important foundation for subsequent construction work. This acceptance process was supervised throughout by the General Station for Quality Supervision of the Chemical Industry, with strict oversight provided by Nanjing Yangzi Petrochemical Engineering Supervision Co., Ltd. During the acceptance process, all members of the acceptance team strictly followed ** and relevant industry standards to conduct a thorough and systematic inspection of key parameters such as the concrete strength of each individual structure, the quality of the rebar work, dimension control, and overall construction quality. It was concluded that the physical quality of each structure met the design requirements and construction specifications, and that all documentation was complete and accurate, which reflects the construction party’s solid technical expertise and rigorous quality management practices. Throughout the project’s progression, the team adhered to the principle of \"safety first, quality foremost,\" systematically coordinating the construction tasks at each stage and precisely controlling the pace of work, thereby ensuring the orderly progression and successful completion of key milestones. The comprehensive acceptance of the main structure of these ten units has not only laid a solid foundation for subsequent large-scale equipment installation, process pipeline laying, electrical and instrumentation connection, as well as system integration testing, but also ensured the continuity and coordination of the overall project construction. Next, the project team will build on this momentum, focusing on key tasks such as the lifting of large-scale equipment, the installation of process pipelines, and the setup of electrical instruments. They will strictly adhere to the deadlines set in the construction plan, work together with all involved parties to coordinate complex operations effectively, uphold strict safety standards, enhance quality control, and optimize the construction process. Every effort will be made to advance the construction efforts and ensure that the project is completed and put into operation on schedule and to a high standard.
