Corrosion issues in turbine rotors
Thread Content
After half a year of use, the second and third stage impellers of the turbine show significant corrosion with many pitted areas – what’s the problem?
After shutdown, has anti-corrosion measures been taken? ~~By the way, how is the water quality? ~~
This requires data analysis on the quality of the steam, as well as the temperature and pressure of the inlet steam
I understand the analysis, but what are the specific details?
I wonder if it has been in use all along, or was it discovered during disassembly after being unused for a long time?
It’s mainly a problem with the quality of the steam.
Impact of steam quality: issues such as water content in the steam, high ion levels in the steam, or fouling on the impeller
Proper protection of the turbine is also necessary during shutdown.
There must be a problem with the steam; running it in this way will cause it to wear out quickly
It’s only been half a year and already this happens; take a look at the material
