Residual Life Assessment

Residual/Remnant Life Assessment of a material is the time during which it retains its fitness-for-service characteristics. Extensive and expansive inspection programmes have to be undertaken, alongside routine operations, in order to monitor the extent of in-service deteriorations. Residual Life Assessment (RLA) studies are conducted on power plant components and their machineries which are subjected to fatigue and/or creep loading conditions.

RLA studies include the of Collection of back ground data and Visual Examination, Survey on past NDT records, Dimension measurements of critical areas, Collection of soot and scales from different section of boilers and pipes, Extensive thickness survey, MPI at critical weld joints, UT of critical weld joints, Replica micro structure examination through in-situ Metallography approach or insitu with digital photography, Hardness survey, Destructive study on selected tubes for chemical analysis, Cross section microscopy, hot tensile test and stress rupture test.

The safe remaining life will be estimated by correlating of test results and operating parameters.

We determine the in-service degradation of critical components of process plants operating under high temperature/ high pressure/ corrosive atmosphere. The technique with specialized software enables real-time component condition monitoring and health assessments.
