    管线钢发展的动态和趋势

      我国管线钢的生产和应用起步较晚,1985年前还没有真正的管线钢生产,当时我国管道的代用钢材主要为国产A3、16Mn和从日本进口的TS52K。然而,近20多年来,我国管线钢的研制、开发和应用得到快速发展。继1989年完成了A、B、X42至X56系列管线钢的研究和应用后,通过西部管道、西气东输和西气东输二线管道等重大管道工程的推动,又先后完成了X60、X70、X80管线钢的生产和应用,并获得了X100和X120的研究成果。
     

      随着石油自然气需求量的不断增加,管道的输送压力和管径也不断地增大,以增加其输送效率。考虑到管道的结构稳定性和安全性,还需增加管壁厚度和进步管材的强度,因此用作这类输送管的管线钢都向着厚规格和高强度方向发展。由于自然气的可压缩性,因而输气管的输送压力要较输油管为高。近年来国外多数输气管道的压力已从早期的4.5~6.4MPa进步到8.0~12MPa,有的管道则达到了14~15.7MPa,从而使输气管的钢级也相应地进步。国外的大口径输气管已普遍采用X70钢级,X80开始进进小规模的使用阶段,X100也研制成功,并着手研制X120。输送酸性自然气的管道用钢已能生产到X65钢级。
