    GB/T14976-2025《输送流体用不锈钢无缝钢管》更新内容，本文件代替GB/T14976-2012《流体输送用不锈钢无缝钢管》、GB/T38810-2020《液化天然气用不锈钢无缝钢管》、GB/T40317-2021《氧气管线用不锈钢无缝钢管》。本文件以GB/T14976-2012为主，整合了GB/T38810-2020、GB/T40317-2021的内容，与GB/T14976-2012相比，除结构调整、内容整合和编辑性改动外，主要技术变化如下：
g）更改了拉伸性能要求（见表3，2012年版的表4）；
h）增加了弯曲试验代替压扁试验要求（见7.4.2）；弯曲试验规定D＞400mm或S＞40mm钢管，可用弯曲试验代替压扁试验，且一组试验含正向、反向弯曲；明确压头直径25mm，室温弯曲180°；要求试验后试样受拉面、侧面无可见裂缝/裂口。
p）增加了拉伸、冲击、弯曲试验试样要求（见第8章）；
