Compressor And Turbine Shaft Repair A User's Viewpoint

Abstract

Very stringent reliability requirements for large unspared compressors and turbines used in refineries and chemical plants demand the use of considerable judgment when repairing and salvaging shafts. Most repair techniques; flame and plasma spray coatings, detonation gun applied coatings, chrome plating, nickel plating, welding, weld overlaying, cutting undersize, sleeving, and new shafting; are used to make the repair urgency, plant reliability, and machine reliability compatible. The objective is to review machine reliability, to classify repair methods, and to help the user select a good sound repair package.
