Entity Serving the Country, Promoting the Nation through Science and Technology

On the occasion of the successful manufacturing and delivery of world-class ultra large wound tube heat exchangers for Sinopec Ningbo Zhenhai Refining and Chemical Localization Project at Dalian Dongfang Yipeng.

The clouds gather summer colors, and the leaves sway with the sound of autumn.
At a time when the whole country is comprehensively studying and implementing the spirit of the Third Plenary Session of the 20th Central Committee of the Communist Party of China, and further deepening reform to write a new chapter in the new era, the key project of the 14th Five Year Plan of China, the 600000 tons/year propane dehydrogenation unit of Sinopec Ningbo Zhenhai Refining and Chemical Co., Ltd.'s high-end synthetic new material project, and the first set of world-class ultra large wound tube heat exchangers, which are domestically developed and applied, were successfully manufactured on August 20, 2024 at Dalian Dongfang Yipeng Equipment Manufacturing Co., Ltd.

We warmly celebrate the successful manufacturing of Sinopec Zhenhai Refining's ultra large wound tube heat exchanger in Dalian Dongfang Yipeng
Industry experts, professors from universities, deans of research institutes, experts and scholars from the field of Sinopec, colleagues from the equipment manufacturing industry, as well as journalists from news media such as Liaoning TV, Liaoning Daily, Beidou Integrated Media, and Lushun TV, jointly attended the solemn and eternal historical moment of the factory acceptance meeting of Sinopec's "Ten Dragon" scientific and technological breakthrough project - Zhenhai Refining and Chemical High Temperature Large Gas Heat Exchanger Engineering Development and Application Project.
The ultra large coiled tube heat exchanger of Sinopec Zhenhai Refining and Chemical's propane dehydrogenation unit has an inner diameter of 6.1 meters, a total length of about 28 meters, and a total metal weight of 850 tons. It is currently the heaviest, largest in diameter, longest in length, largest in heat exchange area, highest in technical requirements, most precise in welding process, and most difficult to manufacture three-dimensional and efficient coiled tube heat exchanger in China and even in the world. The success of its design and manufacturing is of great significance for the large-scale development of the device.

On site acceptance meeting for the localization project of "Development and Application of High Temperature Large scale Gas Heat Exchanger Engineering" at Sinopec Zhenhai Refining and Chemical
This equipment is part of Sinopec's "Ten pronged" localization technology project for the development and application of high-temperature large-scale gas heat exchangers. It poses unprecedented challenges and technical difficulties to Dongfang Yipeng's capabilities in technology design, industry university research cooperation, technology exchange, intelligent manufacturing, process flow, welding technology, processing difficulty, workshop hoisting, component assembly, equipment spraying, packaging and transportation.
From contract signing in the project to manufacturing completion, industry leaders, experts, professors, designers, engineers, and others from Sinopec Material and Equipment Department, Sinopec Guangzhou Engineering Company, Sinopec Zhenhai Refining and Chemical Company, Dalian Dongfang Yipeng, Dalian University of Technology, and Nanjing Sanfang Chemical Equipment Supervision Company have held nine docking meetings, exchange meetings, seminars, and research and development meetings. Dongfang Yipeng always adheres to the concept of technological innovation and industry lean, striving for excellence in quality and scaling new heights in indicators. The design team, welding team, and pipe winding workshop team of the technical center are united and work in the same direction. Faced with many challenges such as the ultra long and overweight of the coiled tube heat exchanger, the special welding structure between the high-temperature end tube plate and the inner hole of the heat exchange tube, and the great difficulty of welding technology and winding, the chairman of the company, Xing Pengwan, personally took the lead and set an example, leading the engineering and technical personnel and operation team to unleash their intelligence, stimulate innovation vitality, and tenaciously strive to overcome difficulties. They constantly improve their processes, optimize their designs, and try every possible way to overcome difficulties. They carefully considered and designed every detail day and night, striving to achieve perfection in every aspect. Every discussion and revision is a collision and sublimation of ideas, laying a solid foundation for ultimate success.

Xing Pengwan, Chairman of Dongfang Yipeng, and Shou Binan, Chief Engineer of China Special Equipment Testing and Research Institute and Chief Expert of Special Equipment Safety Technology of the General Administration of Quality Supervision, Inspection and Quarantine, had a cordial exchange at the expert review group meeting
The device innovatively adopts small-diameter thick tube plate inner hole welding technology at the high temperature end, independently develops new anti-wear and anti vibration pads, and innovatively uses non-contact assembly technology for ultra large and overweight heat exchange tube bundles and shells. We have independently designed a super large thousand ton winding tube machine, an inner hole welding gas protection fixture, and a rapid pressure testing fixture for heat exchange tubes.
Dongfang Yipeng specializes in technical drawings, material procurement, tooling design, production organization, and shift manufacturing. A super large pipe winding clean workshop, where bright white steel pipes shuttle through the large pipe winding machine developed by Yipeng people, weaving into beautiful geometric shapes; The welding rod in the welder's hand emits a dazzling arc, and the welding flowers dance; The customized track carries the tooling independently developed by Yipeng people, and the superb craftsmanship fully embodies the "craftsman spirit" of Yipeng people.
All efforts of accumulation are invincible, and all wisdom is accomplished.
Dongfang Yipeng will complete the manufacturing process from the date of signing the contract on March 6, 2023 to August 20, 2024, almost two months ahead of schedule, successfully completing the first set of world-class ultra large winding tube heat exchanger manufacturing task for the development and localization of Sinopec's high-temperature large-scale gas heat exchanger project. Not only has it refreshed the equipment manufacturing capability of ultra large and efficient coiled tube heat exchangers in China, but it has also added new momentum to the vigorous development of China's petrochemical industry. The emergence of Sinopec's world-class ultra large coiled tube heat exchanger is like a dazzling new star rising in the sky of technology, illuminating the path of technological development. It not only fills the gap in Sinopec's domestic field, but also wins more say for China in the international energy market.

Sinopec Guangzhou Engineering Company, Dongfang Yipeng, and Nanjing Three party Supervision Company held a research and development meeting for on-site office work
