摘　　要：通过宏观检查、显微组织检验、表面质量检验、压扁性能测试和抗拉强度测试对某电厂T91钢管的组织和性能进行了测试和分析。通过测试发现钢管内壁均存在表面裂纹,使得钢管的力学性能降低,不符合GB 5310-2008标准要求。The microstructure and properties of T91 steel pipe in a power plant were tested and analyzed by macro-inspection, microstructure test, surface quality test, flattening performance test and tensile strength test. It is found that there are surface cracks in the inner wall of the steel pipe, which reduces the mechanical properties of the steel pipe. The pipe does not meet the requirements of GB 5310-2008 standard.
