摘　　要：针对某公司转化炉与预转化炉之间的一段压力管线在投用2年后,在弯头与直管连接焊缝处发生开裂的失效情况,对该段压力管线进行了有限元分析,得到了一些有意义的结论。After one pressure pipeline connecting the reborne and pre - rebornerr had been put into production for two years, crack occurred at the weld connecting the elbow and direct pipe in this pipeline. With respect to this phenomenon, finite element analysis for this pressure pipeline was carried out and some meaningful conclusions were obtained.
