Damage Mechanisms Affecting Fixed Equipment in the Fossil Electric Power Industry

WRC Bulletin 490

This bulletin is part of a series of WRC Bulletins that contain the technical background and other information to evaluate damage mechanisms in various industries to facilitate the use of API 579. These bulletins, shown below, will be updated based on the latest knowledge and technology developed for identification of damage mechanisms.

• WRC 488 - Damage Mechanisms Affecting Fixed Equipment In The Pulp And Paper Industry


• WRC 489 - Damage Mechanisms Affecting Fixed Equipment In The Refining Industry


• WRC 490 - Damage Mechanisms Affecting Fixed Equipment In Fossil Electric Power Industry

The series of WRC Bulletins shown above is a valuable tool to assist plant personnel in Risk-Based Inspection studies performed in accordance with ANSI/API RP 580 Risk-Based Inspection because identification of damage mechanism is central to a successful implementation of this technology. In addition, in order to create and maintain an effective equipment reliability or integrity program it is essential that active and potential damage mechanisms are identified.
