Corrosion Control In Industrial Axial Flow Compressors.
Rotor blade, stator vane, and rotor disk or drum corrosion continues to be one of the leading causes of rotor failures in industrial axial flow air compressors, aero derivative turbine engines, and industrial gas turbines. Conventional 12 percent chromium rotor blades and low alloy steel rotors experience accelerated corrosion due to the presence of airborne corrosion contaminants. This paper describes and shows a number of these corrosion related problems noted in various axial flow air compressors. The causes and solutions to those problems are discussed. The corrosion related problems have been found to be very much related to the compressor’s location or local environment. Similar corrosive environments have been found at many compressor installations despite very different geographical locations, applications, or industry (air separation, cogeneration, offshore gas compression, refinery, steel mill, etc.). Various methods for the reduction or elimination of in-service corrosion problems are discussed including inlet filtration, online cleaning, material selection, material treatments, and coatings.
