On April 20, 2009, Nanhua Corporation and Yangzi Petrochemical signed a contract for the manufacture of a large-scale ethylene oxide-ethylene glycol (EO) reactor. Taking responsibility for the localization of large-scale petrochemical key equipments, Nanhua has actively carried out independent innovation, organized experts to carry out research on 12 important topics including material selection, manufacturing, inspection and transportation, and achieved forging quality control; super-large tube plates. Manufacturing; grid fabrication and assembly; tube head welding quality control; heat treatment and non-destructive testing and other major system of major technological breakthroughs, pioneered the tube plate surfacing "turtle" design, grid production of "plum pile" testing, Tube section round the "steering wheel" tires, tube head welding process design and other key achievements. The grid group has applied for national patents on tooling.
Nanhua Machine insisted on carrying out mechanism innovation to make the quality system more perfect. They carefully researched and developed the welding process, selected excellent welders and repeatedly conducted examination training, regularly organized several welding technical exchanges, and strictly controlled the process quality, so that “the quality of each weld can be traced backâ€. The supervisor of the former IHI company in Japan commented: “Your grille is better than Japan.†The 15834 thin-walled duplex steel pipe fittings of the reactor part have a 100% pass rate for the first inspection, and the tube plate has an uneven degree and the cylinder ellipse. A number of key technical indicators such as degrees are superior to foreign ones.
Sinopec attaches great importance to the localization of high-end equipment. Cai Xiyou, a senior vice president of the company, personally took the lead role in the localization of the last ethylene static equipment. Its successful development fully proves that Sinopec has high-end equipment design capabilities, domestic materials can meet the demand for high-end equipment, manufacturing companies have mastered high-strength steel and two-way steel production technology. The research results of Nanhua Chemical in the selection of substitutes for imports have been approved by SEI, Universal, and Beijing Institute of Technology. At present, Nanhua has signed six ethylene oxide reactor manufacturing contracts with a number of petrochemical companies.
