在4台蒸汽发生器辐射段炉管上分别选取多点进行管壁厚度测量，并根据测厚结果进行统计分析，找出在用蒸汽发生器的炉管管壁减薄规律：受热强度越大且位于蒸发段的炉管管壁减薄程度越明显。这是炉管长期处于高温环境下发生蠕变变形所致。如果再加上炉管的介质流动不畅或管壁结垢等因素，这个部位就容易发生炉管鼓包或爆管事故。爆管发生时破口特征为纵向破裂，表面有氧化皮。为保证蒸汽发生器安全、经济运行，要作好炉管蠕变变形测量；要对超期运行的炉管进行材质鉴定，作出金相分析；要保证炉管焊接质量，作好焊缝探伤，以及加强水质管理和炉管状态监测等。
In the four steam generator radiant section of the tube were selected more points to measure the thickness of the pipe wall, and according to the thickness measurement results were statistically analyzed to find out the steam generator tube wall thinning rule: the greater the heat intensity And located in the evaporation section of the furnace tube wall thinning more obvious. This is caused by creep deformation of the furnace tube under high temperature for a long time. If coupled with the tube of the poor flow of media or tube wall scaling and other factors, this area is prone to furnace tube bulge or tube burst accident. Broken pipe burst occurs when the longitudinal rupture, the surface oxide. In order to ensure the safe and economical operation of the steam generator, it is necessary to make measurements of the creep deformation of the furnace tube; to make the material identification of the furnace tube which is overdue and make the metallographic analysis; to ensure the welding quality of the tube and to make the weld flaw detection; Strengthen water quality management and furnace condition monitoring.
