| Abstract: | Comprehensive evaluation of microstructure and property for 12 CrMo 910 main steam piping No1 of unit No4 having been operating 146967 hours in Niangziguan Power Plant has been carried out by using numerous methods, such as chemical component analysis, mechanical test under room temperature, carbide feature and its variation analysis, metallurgical and electronic microscope analysis, creepage damage observation, and persitent strength test etc.. Test results show that the microstructure state and mechanical property of said main steam piping are still perfect after having been operating 149967 hours, satisfying the German standard, can be continuously operating in safety. |
