Following the 2001 national key technical innovation projects -- 45 million tons / year PTA plant titanium equipment localization success manufacture, installation, Nanjing-color Titanium 2004 also awarded the "600,000 tons / year PTA homemade items" processing business, These include : dehydration tower, oxidation reactor, azeotropic towers, a centrifuge for information cans. such as dehydration tower condenser Jiutai Titanium / Stainless composite materials manufacturing of large non-standard equipment. Equipment for the largest diameter 6900 mm, maximum length of 46,000 mm, weight lifting reach 235 tons, China set a PTA project homemade non-standard equipment the most indicators. This series of titanium equipment Domestic Development spectacular success. further lay the Nanjing-Titanium color in the domestic and international-class processing enterprises in the region.
