F041002 Deveropment of Creep Residual Life Assessment Method for Steam pipes with bainito structures

Abstract

For high accuracy residual life assessments and repair cost reduce, Residual creep life Assessment for pipes with bainito structures in STPA22 was developed. the Steam Pipes in the Boilers with bainito structures have a lot of needs cutting down of the repair costs and safty for operating of the power station. We developed method that measuring by using Modefy Mparameter, Hardness and the new technology by longtimetest for creepvoidgroth in testpieces are discovered. Our created method is very accuracy for result compared with conventional only Hardness assessment of the service plants.
