| Abstract: | Brief introduction of principal fundamental of microcomic metal structure and macroscopic mechanics for creep rupture in high temperature pipes of utility boiler were given herein.There were some analysis and probe of creep in main Steam pipe and reheat pipe(hot segment) in service utility boiler.The ordinary method for check of creep crack was illustrated.Incidentally safety assessment and predicting remain life of high temperature pipe were presented also. |
| Keywords: | high-temperature pipe in utility boiler creep crack analysis check method safety assessment remain life |
