Plant inspection is not only to uphold safety in terms equipment integrity but also to optimize the cost of both operation and maintenance. Ultrasonic testing (UT) is a common Non-destructive technique (NDT) to monitor corrosion rates of the equipments. Current practices of UT only based on point thickness gauging technique to obtain corrosion rates. The utilization of this method can be optimized by area based thickness inspection. This innovation can produce accurate corrosion rate and reliable 3- dimension model for Fitness-for-service (FFS) level 3 assessment by using fmite element method. The objective of this project is to develop an effective corrosion monitoring tools by innovating conventional A -scan ultrasonic testing (UT) thickness gauging technique. A series of UT experiment with different corrosion profile will be done. Actual corrosion rate ( CR act) as a control variable is measured by weighting the mass loss of the sample. UT thickness measurement is applied by using the specified method to get the corrosion rate ( CR .,..,) derived from area based inspection and compared with current application ( CR point)- The corrosion profile also can be produced and will be analyzed further by finite element analysis in FFS assessment The result shows that UT innovation can produce high accuracy of corrosion rate as high as intrusive mass loss coupon method compared with current practice. A precise 3- dimension corrosion profile that resembles the actual condition as well can be developed that is practical to produce an accurate FFS level 3 assessments. The conclusion is the innovation of UT in monitoring corrosion has high potential to produce the reliable result in cost effective operation.
