March 2010 Turbine Tip: Turbine Corrosion Conditions
Minimizing corrosion in a steam turbine is not limited to the design and operation of steam cycle equipment. Contaminants can cause issues during 1) manufacturing (from fluids and lubricants), 2) storage (from preservatives), 3) installation (from exposure to pollutants, preseratives, and cleaners), and 4) NDE (cleaning and NDT chemicals can produce corrosion). Preservatives, cleaning and machining fluids, and NDT chemicals may contain sulfur or chlorine which can form acids when decomposed. Local concentrations of these acids in some of the best alloys can cause SCC (Stress Corrosion Cracking). SCC has led to turbine rotor failure primarily on rotors with shrunk on discs (at their key ways) and blade or bucket rotor steeples. It is extremely important to have good boiler chemistry, and any copper components in a steam cycle design should be eliminated.
