Evaluating the condition remaining life of older power

Creep-fatigue analysis places an important role in the life assessment activity of power plant equipment.In the U.S.A.an approach to the creep-fatigue design and remaining life calculation was develop in the ASME Boiler and Pressure Vessel Code,Section III,Code Case N-47 which is essentially based on the linear damage summation method given Creep Life Assessment of USC Boiler Tubes Pressure Kubushiro,K.Creep Life Assessment of USC Boiler Tubes.
