Life Assessment Methods for Pressure Bearing Components in Power Station Boiler

PAN Bo-ding 1,PAN Jin-ping 1,CHENG Hong-hui 2,SHEN Mei-hua 1,LI Yong 1 (1.Jiaxing Special Equipment Inspection Institute,Jiaxing 314000,China;2.College of Mechanical Engineering,Yangzhou University,Yangzhou 225127,China)  
Domestic and overseas life assessment methods for the pressure bearing components in power station boiler under operation conditions were reviewed.Two types of assessment methods were focused,i.e.,extrapolating the data of conventional creep rupture test,and measuring creep deformation and crack propagation.The first type methods included extrapolation method by creep rupture strength curve,time-temperature parameters method,Robinson life consumption rule and so on.The second type methods included θ method,C projection method,gradual extrapolation method by creep curve,assessment method by creep rupture and crack propagation ans so on.
