Precision steel pipe has always been an important aspect of China's industrial production, with the development of society, precision steel tube product structure optimization project has officially started. Precision seamless steel tube production specializing in the production of steel bar Division units, precision steel tubing plant products are widely used in power station boiler, petroleum, chemical industry and other fields, some products are exported to the United States and other countries and regions and won the domestic and foreign users. Currently, precision steel tube factory has become the domestic manufacture of boiler steel pipe variety, most specifications of one of the main production plant. As part of city Changjiang Road Cross-River tunnel project and Hutong in the planning required for railway construction, Baosteel's decision to relocate the plant as a whole, and to approve the implementation of precision steel tube product structure optimization project, the project built in the Baoshan region West of hull plate processing center in this part. Precision steel tubes after completion of product structure optimization, mainly the production of automotive tubes, tubes for use in aircraft, military use of tubes, high-pressure boiler tubes, oil casing in five categories, and seamless steel tube plant 140 Unit develop a complementary, will further enhance the overall competitiveness of Baosteel steel pipe products.
