For high accuracy residual life assessments, and prolongation periodical inspection for high-temperature parts in boilers, there are a lot of needs finding maximum damage parts for large size pipes in boiler. We developed method that measuring by laser instrument , using elastic analysis by FEM and creep damage analysis by FEM, and observed cross section cut scrap in service plants. Result of this FEM Analysis and this section microstructure are very similar. Our created method is accuracy and and simple.
