A procedure of estimating failure probability is demonstrated for a pressurized pipe of Cr-Mo steel used at 538℃. Probabilistic fracture mechanics were employed considering variations of pressure loading, material properties and geometry. Distributions of the major variables were reflected in Monte Carlo simulation by statistical analyses of implemented data obtained by previous experiments. Failure probability as a function of operating time was determined. Sensitivity analysis for each input variable was also conducted to understand the most influencing variables to the residual life analysis.
