摘　　要：介绍了天津钢管集团股份有限公司A335P22大口径核电管研制的工艺过程及产品性能,化学成分、室温力学性能以及高温拉伸性能均满足核电技术协议要求。并与日本住友同类产品进行性能解剖分析对比,结果表明:我公司生产A335P22大口径核电管各项性能指标与日本住友产品相比水平相当,达到国际领先水平。The technology process, for the seamless steel pipe A335P22 used in nuclear power plant, developed by TPCO, as well as the product properties were introduced. It was found that the chemical compositions, mechanical properties at room temperature, and tensile properties at high temperature had all met the requirements in the technical agreement with the nuclear power plant. Detailed performance comparisons with the similar product manufactured by Japan compet- itor Sumitomo company showed that the pipe A335P22 manufactured by TPCO had the fairly e- quivalent product properties with Sumitomo, thus reaching the international advanced level.
