【摘要】：对某电厂高压导汽管低硬度区管段进行了常规试验,通过常规试验数据对其进行蠕变损伤开裂分析和扩展寿命评估。结果表明,在常规力学性能低于标准要求时,温度降低至540℃的情况下,该高压导汽管的蠕变损伤开裂寿命约为5914 h。
[Abstract]:In this paper, a conventional test was carried out on the low hardness section of a high pressure steam guide pipe in a power plant. The creep damage cracking analysis and expansion life evaluation were carried out through the conventional test data. The results show that when the conventional mechanical properties are below the standard requirements, When the temperature is reduced to 540 鈩，
