It is also an equipment supplier for large multinational energy and chemical groups such as BASF SE and Saudi Basic Industries Corporation (SABIC).

The company is located in the Equipment Manufacturing Cluster Industrial Park in the southern part of Wuhan, a city known as the "thoroughfare of nine provinces". It has the advantages of convenient transportation by river - sea waterway, railway, and road, with the Wuhan Jinkou Yangtze River Deep - Water Port, the Wuhan Logistics Assembly Station of the China - Europe Railway Express, and the intersection of the Beijing - Zhuhai Expressway and the Shanghai - Chengdu Expressway nearby. Adjacent to Wuhan Huangjiahu University Town, it has unique geographical and cultural advantages.

The company adheres to the principle that product innovation and services must meet user needs, create value for customers, and attaches great importance to the combination of industry, education, research, and application to achieve innovative development. Over the years, the company has carried out cooperative research and development on projects such as the application of safety technology for high - efficiency heat exchangers under high - temperature, high - pressure, and hydrogen - containing conditions, welding and forming technology for non - ferrous metal composite materials, fluidized - bed reactors, micro - reactors, and reactors with special structures with many scientific research institutions and universities, including Tianjin University, Dalian University of Technology, East China University of Science and Technology, Wuhan Institute of Technology, Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, Institute of Process Engineering of the Chinese Academy of Sciences, and Fujian Institute of Research on the Structure of Matter of the Chinese Academy of Sciences. Currently, the company has obtained more than 50 authorized patents in special products, process technologies, special structures, and components.

Relying on a united and enterprising team, advanced production and manufacturing equipment, and a sound quality assurance system, the company has formed a series of pressure vessel products mainly including wound - tube heat exchangers, large - scale shell - and - tube heat exchangers, and large - scale tubular reactors, covering the manufacturing of pressure vessels made of materials such as low - alloy low - temperature steel, low - alloy high - strength steel, austenitic stainless steel, ferritic stainless steel, austenitic - ferritic duplex stainless steel, nickel and nickel - based alloys, titanium and titanium alloys, zirconium, and aluminum. It has unique thermal design software and a reliable technical system to ensure safety and economy. The products are widely used in industries such as coal chemical industry, new energy, integrated refining and chemical industry, polysilicon, LNG, and power. The users are spread across countries such as China, the United States, India, Russia, Kazakhstan, Uzbekistan, Iran, Iraq, Oman, Zambia, Brunei, and Pakistan.
