Materials in Centrifugal Compressor and Steam Turbines: Selection, Processing, and Repair
MetadataShow full item record
Materials selection is significant with respect to performance, reliability, and longevity of turbomachinery, particularly given the increasing severity of the process environments. The trends are that the selection is becoming a cooperative effort between the OEM’s and the customers and it is vital that all parties understand the implications of the materials selection and necessary manufacturing processes. This course reviews the material selection for major components for centrifugal compressors and steam turbines coving topics such as materials of construction, heat treatments, properties, fabrication and manufacturing methods, inspection methods, and compliance with industry specifications such as API and NACE along with other special requirements. Going beyond new equipment, the course will touch on the identification of damage mechanisms through root cause analysis and then delve into the procedures and documentation required to restore the components to operating condition. The course will end with a discussion of various coatings and surface treatments that can also be used to enhance the performance and/or longevity of the equipment.
