摘要

分析了耐热 12Kh1MF 钢在 TPP（火力发电厂）蒸汽管道弯管中长期运行后的机械特性和结构特征。确定了弯管不同区域金属技术状态的变化以及整个管壁厚度的各向异性。研究发现，在靠近管道外表面的弯管拉伸区，钢材的退化程度比其他区域更严重，这是由于该区域处于最有利于蠕变的工作条件下。

The Structural-Mechanical State of 12Kh1MF Steel of TPP Pipeline Bend after Long-Term Operation

The mechanical characteristics and structural features of the heat-resistant 12Kh1MF steel after long-term operation in a bend of the TPP (thermal power plants) steam pipelines were analyzed. The change in the technical state of the metal of different zones of the bend and the anisotropy of properties across the pipe wall thickness were established. It was found that in the stretched zone of the bend near the outer surface of the pipe the steel degraded more intense than in other zones, which was due to the most favorable operating conditions for creep.
