Hefei General Machinery Research Institute and other units in Anhui Province after three years of research and research, recently successfully developed and built a large-scale low-temperature ethylene spherical tank with independent intellectual property rights.
Ethylene spherical tank is the key storage device in the ethylene cracking device. When it is used, the operating pressure is high, the temperature is low, and the safety requirement is high. A reliable cold-keeping device needs to be installed. This puts many technical problems in the design, material selection, manufacture, and construction of ethylene spherical tanks. Hefei General Institute and other units have overcome key technologies and process problems in the process of construction, welding, heat treatment, etc. of large-scale low-temperature ethylene spherical tanks in design and construction, and independently developed complete sets of application technology for manufacturing pressure vessels using -50°C low-temperature steel. The first fully domestically produced 2,000 cubic meters of low-temperature ethylene spherical tanks was constructed in China, which broke the import-dependent situation of large-scale low-temperature ethylene ball tanks in China. Up to now, the hospital has signed cooperation agreements with PetroChina Dushanzi Petrochemical, Jiujiang Petrochemical, Tianjin Petrochemical and other companies.
