en.Wedoany.com Reported - Recently, the construction of the Jintang New Materials Project under Rongsheng Petrochemical achieved a major technological breakthrough. According to CCTV News, the project's key supporting facility—the cross-sea petrochemical pipe gallery—successfully completed China's first large-span, large-tonnage offshore high-altitude precision hoisting in Zhoushan, Zhejiang Province.
The single module hoisted weighed 515 tons and measured 43 meters in length, setting a new tonnage record for similar construction in China and filling a technical gap in the country's offshore large-tonnage pipe gallery construction.
As a key step in extending Rongsheng Petrochemical's industrial chain, the Jintang New Materials Project has a total investment of approximately 67.5 billion yuan and plans to build 27 main production units and 16 public supporting facilities. Upon full operation, the project is expected to achieve an annual output value of 91.7 billion yuan, focusing on the development of new material industrial chains such as high-performance resins, biodegradable plastics, specialty polyesters, and high-end fibers.
The successful completion of the cross-sea pipe gallery hoisting not only marks a significant technical milestone for the project but also demonstrates Rongsheng Petrochemical's leading capabilities in the construction of ultra-large petrochemical engineering equipment, laying a solid foundation for the project's high-quality commissioning.
Recently, all 16 large spherical tanks for the Jintang New Materials Project of Rongsheng New Materials (Zhoushan) Co., Ltd., manufactured by LS Heavy Equipment, were successfully capped, marking a key milestone in the construction of the project's core storage and transportation facilities and laying the groundwork for subsequent equipment installation and on-schedule commissioning.
This project is a benchmark project for the key new materials industry in the Zhoushan region, with plans to build 27 main units and 16 public facilities, focusing on the development of high-end chemical industrial chains such as low-carbon polyolefins, fine chemicals, high-performance resins, engineering plastics, biodegradable plastics, specialty polyurethanes, and new fiber materials. LS Heavy Equipment manufactured 8 ethylene spherical tanks and 8 propylene spherical tanks, each with a capacity of 3,000 m³, serving as the core supporting facilities for the storage and transportation of project raw materials and products, and are among the first batch of supporting facilities to be put into use.
Currently, the three ethylene spherical tanks that have completed welding have all achieved first-grade qualification and zero rework in the initial TOFD non-destructive testing, fully demonstrating LS Heavy Equipment's refined management level and excellent construction quality. The Spherical Tank Engineering Branch stated that it will continue to adhere to safety bottom lines and strictly control quality standards, steadily and efficiently advancing the welding work of the remaining spherical tanks to ensure the project's early commissioning and support the high-quality development of the regional new materials industry.
The Jintang New Materials Project, invested by Rongsheng Holding Group and managed by Rongsheng New Materials (Zhoushan) Co., Ltd., is located on Jintang Island in Dinghai District, Zhoushan City, serving as an expansion area of the Zhoushan Green Petrochemical Base. The project focuses on developing high-end industrial chains such as low-carbon polyolefins, fine chemicals, high-performance resins, engineering plastics, and biodegradable plastics. It plans to build 27 main units and 16 public facilities. Among these, 12 technologies are independently developed by the company, and 7 are advanced Chinese technologies, with most achieving domestic substitution.
