| Abstract: | This article describes the structure of the air exhaust pipe of the superheater, and the mac- roscopic characteristics of the exhaust pipe cracking . From the tube socket structure, working envi- ronment, the stress analysis believe that the main reason of the tube socket cracking due to long - term effects of vibration fatigue stress and thermal stress. It make reliable tube replacement process according to the actual situation. |
