近日,国家重点工程西气东输二线用钢管——X80钢级、直径1219毫米×18.4毫米螺旋钢管,在中国石油物资装备(集团)总公司华北装备制造事业部第一机械厂华油钢管公司螺旋焊管生产线开始投入批量生产。据记者了解,西气东输二线由一条干线和九条支线组成,用管总量约440多万吨,其中螺旋钢管占380多万吨,将大批量应用X80钢级、直径1219毫米×18.4毫米螺旋钢管。在这项宏伟的管道建设工程中。管线规模、输送压力、输送距离、应用钢材级别等各项技术指标卜均填补国内空白,达到国际领先水平。
Recently, the State Key Project of the Second West-East Gas Pipeline - X80 steel grade, diameter 1219 mm × 18.4 mm spiral steel pipe in the China Petroleum Materials and Equipment (Group) Corporation North China Equipment Manufacturing Division First Machinery Plant Huayou Steel Pipe Company Spiral welded pipe production line began to put into mass production. According to report, the second line of the West-East Gas Pipeline consists of a trunk line and nine branch lines. The total amount of pipe is about 4.4 million tons, of which the spiral pipe accounts for more than 3.8 million tons. The X80 steel grade will be used in large quantities and the diameter will be 1219 mm × 18.4 mm Spiral pipe. In this magnificent pipeline construction project. Pipeline size, delivery pressure, delivery distance, the application of steel grade and other technical indicators Bu Bu fill the gap, reached the international advanced level.
