【Haichuan Equipment Guessing Game】Traveling thousands of miles to Africa, the first refinery is of key importance
Thread Content
Do you know what material this device is made of?
It’s hard to say; for ships and offshore engineering projects, it’s standard practice to prefabricate the components in various factories and then assemble them together at the shipyard or the destination. For those with low technical complexity, choose a low-cost option for production ； For those with technical confidentiality and high content, adjustments should be made upon arrival at the destination. You can search for the YAMAL project.
A factory this small daring to take on such large equipment – one has to be impressed. You can’t determine the material just by looking at its appearance!
Is the poster sure they’re going to Africa? Use the little boat from the photo!

The world’s largest atmospheric pressure tower, weighing around 2,300 tons, was transported to Nigeria; the welding skills of the workers there earned praise from clients. Report by our correspondent Wang Jue, with contributions from Zhang Chaoliang and Yao Shijie. At 7 o’clock yesterday, accompanied by a long blast of the horn, the fully assembled world’s largest atmospheric pressure tower was shipped from Xize Wharf in Xiangshan Port to Nigeria. This atmospheric pressure tower was manufactured by Ningbo Tianyi Petrochemical Heavy Equipment Manufacturing Co., Ltd., located in Jiaochuan Sub-district, Zhenhai. It has a diameter of 12 meters, a length of about 112 meters, and a weight of around 2,300 tons – all of which set new records in China for the diameter, length, and weight of atmospheric pressure towers exported abroad. “The volume of this atmospheric pressure tower is roughly equivalent to that of 1,000 cars; nearly a hundred workers were involved in its construction, which took over a year. ”Li Gang, project manager of Tianyi Petrochemical, explained that via the Maritime Silk Road, the atmospheric pressure tower will travel from the west coast of the Pacific to the east coast of the Atlantic, reaching Lagos State in western Nigeria, to be used in the ongoing Dangote Refinery project there. The refinery is designed to process 650,000 barrels of crude oil per day, and its single-unit processing capacity is currently the highest in the world. “The atmospheric pressure tower is the ‘heart’ of an oil refinery, and very high standards are required for the quality of its welding work. If the temperature of the materials and the environmental humidity are not carefully controlled, welding defects can easily occur. ”Xi Xiubin, the welding responsibility engineer at Tianyi Petrochemical, said that after receiving orders from Africa, Tianyi Petrochemical assembled engineering designers and technical personnel to optimize designs related to materials, layout, and welding, and applied concepts such as green and low-carbon practices throughout the production process. During the welding process, a team of over 50 people formed a super “welder” squad. Many of them have received honors such as Municipal Model Worker, Municipal Outstanding Worker, and Municipal \"Port City Craftsman\". The team overcame difficulties such as the use of multiple materials in the equipment base metal, as well as the high requirements and complexity associated with manufacturing. They used three types of welding materials – carbon steel, stainless steel, and nickel-based alloys – while ensuring that various parameters such as the ferrite content in the welds and their chemical composition met the technical specifications. The team welded various materials for a total length of about 6 kilometers, which is equivalent to 15 laps around a standard track with a circumference of 400 meters. “Tianyi Petrochemical strictly follows the inspection and testing plans established by all parties, focuses on quality control at various stages of production, and ensures high standards for the quality of atmospheric distillation units as well as their manufacturing timeline, earning praise from customer representatives. ”Suresh Kumar, quality supervisor for the Dangote petroleum refining project in Nigeria, said. The reporter learned that over the years, Tianyi Petrochemical has supplied dozens of thousand-ton-class pressure vessels to clients both at home and abroad, and its products have been applied in countries along the Belt and Road Initiative such as Russia, Brunei, and Kazakhstan.
