摘要
对应用于西气东输二线管道工程的典型X80钢级18.4mm×1550mm板卷的化学成分、拉伸性能、冲击性能等试验结果进行了分析。结果表明:板卷的强度分布表现出各向异性,即与板卷轧制方向成90°方向的强度最高,而沿板卷轧制方向、与板卷轧制方向成60°以及与板卷轧制方向成30°方向基本上相差不大,均相对较低,冲击性能和落锤撕裂性能良好。
The chemical analysis, tensile test properties, charpy impact properties and DWTT results for typical grade X80 18.4 mm × 1550 mm coil used in the 2nd West - East Pipeline Project were analyzed. The results show that the strength distribution is anisotropic, and the strength at 90°is the highest, the ones at 0°, 30°and 60° are lower. The low temperature charpy impact test and DWTT results are very good.
