Life Assessment of Super Heater and Reheater Tubes through Steam Side Oxide Scale Measurements-CPRI Experience
Keywords:
No Keywords.Abstract
High temperature pressure parts of boilers where in creep is the major damage mechanism, are required to be assessed periodically (after 100000 hrs) for remaining life. Creep life estimation could be made by destructive and non destructive techniques. This paper highlights the use of ultrasonic technique for assessment of creep life of SH/RH tubes by in-situ steam side oxide scale measurement. The scope for future studies are also given in the paper.Downloads
