Which domestic companies are capable of manufacturing urea synthesis towers?

There are also manufacturers in Tianjin that produce products in this area, and the performance of their products is quite good

One layer is also fine! China National First Heavy Machinery Group Corporation (hereinafter referred to as CNFMC) was formerly known as the First Heavy Machinery Factory. It was established in 1954 and began full-scale production in June 1960 after passing the relevant inspections. It was the first large-scale heavy equipment manufacturing enterprise built during China’s First Five-Year Plan period. Today, it is one of the 53 key state-owned enterprises under direct central government management that are vital to the country’s economy and national development. Yichang mainly provides major complete sets of technical equipment, high-tech products, and technical services for industries such as steel, electricity, automobiles, mining, petrochemicals, nuclear power, and transportation, as well as for the defense and military sectors, and it is also engaged in related international trade. Eight main categories of products have been developed, including metallurgical equipment represented by cold- and warm-temperature steel continuous rolling mills, medium and heavy plate rolling mills, continuous casting machines, and converters; petrochemical vessels represented by hydrogenation reactors and coal-to-oil reactors; nuclear island equipment represented by nuclear reactor pressure vessels and pressure regulators; large-scale power generation equipment castings and forgings represented by Three Gorges turbine blades, upper crowns, and high-, medium-, and low-pressure rotors; industrial and mining components represented by extra-large forged and cast steel rolls as well as cast iron rolls; and heavy forging equipment represented by 5,000-ton large mechanical presses and hot die forging. For over 50 years, Yizhong has made significant contributions to the development of China’s national economy and defense industry. It has supplied more than a million tons of machinery products, filled over 300 technical gaps in industrial products, developed more than 240 new products, and achieved many \"firsts in China\". It has built the renowned \"Yizhong\" brand, and has manufactured China’s first sets of 1700 and 1780 millimeter hot rolling mills, a 12,500-ton free-forging hydraulic press, a 30,000-ton die-casting hydraulic press, an 1,150-millimeter square billet rolling mill, and a 2,800-millimeter cold and hot aluminum sheet rolling mill ； Since the 1980s, IDRO has actively introduced advanced foreign technologies. Through joint design and cooperative production, it has successfully developed dozens of advanced products, including 2050-mm hot continuous rolling mills, 1900-mm slab continuous casting machines, the 2800XPB large-scale mining excavator, Komatsu presses – key equipment used in automobile body manufacturing lines, large-scale petroleum cracking equipment such as hot-wall hydrogenation reactors, 3000-ton vertical plate bending machines, rotors for high-, medium-, and low-pressure power plants with a capacity of 300,000 kilowatts, and 300-megawatt nuclear pressure vessels. The company has thus secured a monopoly on the domestic market for hydrogenation reactors made from forged and welded structures ； In recent years, Yizhong has designed and manufactured its own 1780-mm cold continuous rolling mills and leveling units for Ansteel, which feature independent intellectual property rights. It has successfully developed new parent materials for hot-wall hydrogenation reactors as well as reactors with a capacity of 1,000 tons. The company took on China’s first experimental fast reactor project, manufactured the world’s first set of coal liquefaction reactors weighing 2,000 tons for Shenhua Group, and produced the world’s largest and most advanced 15,000-ton free-forging hydraulic press, which came online at the end of 2006. Additionally, it is currently working on the pressure vessels for Pakistan’s second phase of 300MW nuclear reactors and the Qinshan 600MW nuclear reactor. All these achievements have placed Yizhong among the world’s leading manufacturers. Yizhong attaches great importance to product quality, has established a scientific quality assurance system as well as advanced methods for product quality testing. It has obtained various manufacturing licenses, including those from ASME, for pressure vessels and civil nuclear pressure equipment, as well as from British LR, American ABS, Norwegian DNV, and Chinese CCS classification societies. The company has also passed ISO9001 and GJB/Z9001 quality system certifications. The product quality of Yizhong remains at a leading level in China, with some products reaching international standards. This post was last edited by yuchenjoy2008 on 2009-3-21 08:47.]

Dalian Iceberg Group Jinzhou Heavy Machinery Co., Ltd

At present, the four units in the high-pressure sector for large-scale fertilizer production are essentially monopolized by Dalian Jinzhou Heavy Industry! !

Dalian Iceberg Group Jinzhou Heavy Machinery Co., Ltd., Nanhua Machinery, Xi’an 524, and Yizhong – all of them can handle this task!! Due to an accident involving Nanhua Machinery’s products a few years ago, 90% of such orders are now handled by Dalian Jinzhong; however, last year Nanhua started receiving orders again!!

I heard that Zhangjiagang Chemical Machinery Factory can do it too; I have a friend who works there and says they have done it before
