Abstract


Application of standard for remaining life assessment at boiler tube of steam powered electrical generator unit by
non-destructive test (NDT), up to now has been very important. The condition of boiler tube used in electrical
generator in Indonesia has reached its design limit and even some of them have replaced. This research used nondestructive
test methods by SNI, JIS and API standard and was conducted at boiler unit II in Indonesia, that has
already in 25 years operated. This method consists of several technique approaches that are: replica methods
(microstructure), hardness test, outside diameter measurement (OD), and wall thickness measurement. After
assessment and analysis, the results of non destructive test methods showed that the remaining life of boiler tube
is 100.000 to 120.000 operation hours.
