摘要
通过对过火后的某输油管线进行现场金相组织分析和里氏硬度试验,推测其过火时所达到的温度和对其组织和力学性能的影响,并以此为据判断能否继续使用。
In order to speculate the effect on metallographic and mechanical properties after fired,microstrueture analysis and Leeb hardness on-site test are taken out on a fired pipeline. A feasibility judgment of the ability of continuing to be used is taken.
