Abstract

Traditional Power Law equations and modern creep equations were evaluated to estimate long term creep life of Grade 22 material. Evaluation of models made on a short-term database for predicting its capacity of precise long-term creep life. Linear trend line curve fitting method used for extrapolation of data for long-term creep life. Open SourceNRIM creep rupture data for Grade 22tube in annealed/tempered condition and plates in quenched/tempered plates used in this evaluation. This evaluation is helpful for power plant industries for selecting an economically viable and precise model.
