X20CrMoWV121钢主蒸汽管长期运行后寿命研究
The research on remaining life of X20CrMoWV121 main steam pipe after long term service
【摘要】 本文通过蠕变断裂试验和持久强度试验,研究125MW机组长期运行后X20CrMoWV121钢主蒸汽管的蠕变变形方程和蠕变曲线,根据持久强度外推法和θ函数法进行剩余寿命研究,该主蒸汽管道在以蠕变为失效模式下,满足继续安全运行10万小时的要求。
【Abstract】 Using creep rupture test and endurance strength test, the creep deformation equation and creep curve of X20CrMoWV121 steel was studied. Following endurance strength extrapolation and θ function method, the main steam pipe can still run safely for 105 hours, on the basis that the failure pattern is creep.
