摘　　要：屏式过热器管产生周向裂纹是比较少见的。经　综合试验分析，认为张店热电厂３号炉屏式过热器管因腐蚀热疲劳而产生周向裂纹并引起　管子泄漏。The circumferential cracks occurred on platen superheater tubes are comparatively uncommon. Through comprehensive test and analysis, it is considered that the horizontal cracks occurred on platen superheater tubes were due to corrosion heat fatigue, and resulted in leakage of tubes.
