Evaluation of Reformer Tubes Degradation after Long Term Operation

Since the estimation of remnant life by deterministic methods is expensive and time consuming, in this study the remnant life is evaluated using structural reliability analysis and distribution analysis. The remnant life of the reformer tubes was studiedby using the creep lifetime model and Monte C...
