On December 31, 2025, the Tarim polypropylene project of the fourth branch reached a significant milestone: the construction of the intermediate buffer silo unit, with a total height of 41.6 meters, was successfully completed. This achievement laid a solid foundation for the subsequent individual testing of the main compressors and the system integration tests, demonstrating the project team’s strong construction capabilities in complex low-temperature environments. Since the launch of the labor competition titled \"Winning the Battle Against Winter Construction Challenges\" for the Tarim polypropylene project, the Party branch of the Xinjiang project under the Fourth Branch has fully leveraged the role of Party building in providing guidance; it formed Party member task forces and youth task forces to promote close integration between Party building efforts and construction activities, thereby fostering a strong collective effort among all employees to overcome difficulties. The construction task for this intermediate buffer bin unit is extensive, involving 86.76 tons of steel structure installation, 10.5 tons for the fabrication and installation of ladder guards, 17.56 tons for the laying of steel grating, as well as 6,891 inches of welding work on the process pipelines. The project team has always adhered to the principle of keeping progress, quality, and safety in sync, strictly implementing safety plans for construction in low-temperature conditions to establish a solid safety barrier for winter construction. Zhu Yanan’s construction team from the installation company is responsible for this construction task, and it faces numerous technical challenges: the pipelines used are mainly made of stainless steel, and they include a large number of thin-walled air supply pipelines with a wall thickness of only 3 mm, which imposes strict requirements on the precision of welding techniques and the quality of installation. To balance construction efficiency with project quality, the team strictly adheres to the construction technical instructions and process specification sheets. For stainless steel pipelines, a double argon shielded welding method is employed, and an innovative construction approach of \"integral prefabrication on the ground + simultaneous lifting using two machines\" is implemented. This not only reduces the risks associated with working at heights but also significantly improves installation accuracy and construction efficiency. In low-temperature winter conditions, operators use traction ropes for precise adjustments to ensure that the installation deviations of all components remain strictly within the limits permitted by the specifications.
