| Abstract: | A comprehensive and systematic test was proceeded to steel 12Cr1MoV straight and bent pipe of main steam pipe which had been operating for 320,000 hours.Using obtained data and observed phenomenon through material analysis,it was estimated that total accumulating operating life would be 334,600 hours for bent pipes and 368,200 hours for straight pipes. |
| Keywords: | main steam pipe mechanical property carbide creep hole residual life |
