On September 22, the first domestic large-scale ethylene oxide (EO) reactor designed by Nanjing Chemical Industry Co., Ltd. Chemical Machinery Plant Manufacturing and Engineering Construction Co., Ltd. was completed. The key technical indicators of the equipment reached the world's advanced level, indicating that China’s long-term dependence Imported large-scale high-end static equipment to achieve localization.
Raschel lace machines indicate a big machines range, which
includes Multibar Raschel Machines, Raschel Jacqaurd Machines, Fall-plate Raschel
Machines, Multibar Jacqaurd Raschel Machines and others. Multibar Raschel machines
indicate that pattern bars amount above 18, while Raschel Jacquard Machines usually
refer to curtain machine, such as TH-4/1F type and its upgraded machine types Besides,
high speed elastic textile machines RSJ4/1 and RSJ5/1 are also belong to Raschel
Jacquard Machine.

Large-scale EO reactors are complex in structure, technically demanding, and difficult to manufacture. They used to depend on imports in the past. In April 2009, as a major equipment localization project of the group company, Nanhua Company signed a large-scale EO reactor manufacturing contract with Yangzi Petrochemical and assumed the responsibility for the localization of large-scale ethylene static equipment. Cai Xiyou, senior vice president of the company, served as the research group. Leader.
Nanhua Machine Factory actively carried out independent innovation and organized experts to carry out 12 key research topics such as material selection, manufacturing, and inspection. It achieved major technical breakthroughs such as forging quality control and super-large tube plate manufacturing, and pioneered the "tortoise" of tube plate surfacing. The key achievements such as "Design" and "Plum Pile" testing made on the grid. The large-scale EO reactor has been manufactured with a diameter of 7 meters, a length of 22 meters and a weight of 850 tons. A number of key technologies such as the 100% pass rate for welding inspection of 15,843 thin-walled, two-phase steel pipe heads and tube plate ovality The index is better than abroad.
At present, the South Chemical Plant has signed six ethylene oxide reactor manufacturing contracts with a number of petrochemical companies. According to reports, the cost of manufacturing a large EO reactor can be saved by more than 30% after localization.
