1993近中日天津的东部出现了一片现代化的厂房，这就是国家“八五”期间重点工程天津钢管公司，这是一个具有世并先进设备、先进技术水平的特大型企业，形成南有宝钢，北有天管的冶金现代化企业格局。天津钢管公司的建成，结束了油套管长期依赖国外进口的历史，标志着改革开放? In 1993, a modernized factory building appeared in the east of Tianjin, which is the key project of the Tianjin Steel Pipe Company during the “8th Five-Year Plan” period of the country. This is a super large-scale enterprise with world-class advanced equipment and advanced technology, forming Baosteel in the south. There is a metallurgical modern enterprise structure in the north. The completion of the Tianjin Pipe Company ended the history of long-term dependence of oil casings on foreign imports, marking the reform and opening up.
