Analysis Of Ni And Fe-Based Alloys For Turbine Seal Ring Applications, Dawei She
Analysis Of Ni And Fe-Based Alloys For Turbine Seal Ring Applications, Dawei She
USF Tampa Graduate Theses and Dissertations
Metal sealing rings have been used widely in compressors, turbines and hydraulic devices. Such rings can extend out due to elasticity, and keep close contact with the valve wall, resulting in the formation of a functional seal under pressure. In this project, the failure of metal sealing rings is considered. Sealing component failure due to stress relaxation can threaten the safety of the whole steam turbine. The object of this study was to examine the stress relaxation response and corresponding changes in microstructure of metal sealing rings used in nuclear steam turbine under high temperature and applied stress. The two …
Failure Analysis Of High Nickel Alloy Steel Seal Ring Used In Turbomachinery, Wenbo Wang
Failure Analysis Of High Nickel Alloy Steel Seal Ring Used In Turbomachinery, Wenbo Wang
USF Tampa Graduate Theses and Dissertations
The system of upper high nickel alloying steel seal ring and lower high nickel alloying steel seal ring, installed in the grooves of turbine, can extend out and fit with the wall of valve cage, resulting in forming a good seal under the pressure. In the project, the failure steel seal ring is considered. This situation had threatened the safety of the whole steam turbine system. The purpose of this study is to identify the failure cause of the steel seal ring used in nuclear steam turbines. New high nickel steel alloy seal ring was compared with the failed seal …
