Title: Acoustic emission monitoring of high-energy steam piping, Volume 1: Acoustic emission monitoring guidelines for hot reheat piping. Final report

Abstract

Fossil plant high energy piping systems are susceptible to severe creep damage and occasional catastrophic failure. Such nondestructive examination (NDE) methods as ultrasonic, radiographic, magnetic particle, and liquid penetrant testing can be used to inspect piping, but these techniques are costly and require complete removal of insulation. The guidelines in this report describe the use of an alternative NDE method, acoustic emission (AE) monitoring, to detect, locate, and rank AE sources in hot reheat lines that are activated by high temperature power plant operations. AE monitoring is intended to identify the AE sources whose driving mechanism may detrimentally impact the integrity of the pipe pressure boundary so that follow-on inspection using other NDE techniques can then concentrate on suspect locations and quantify material defects. The guidelines in this report include recommended analysis methods, analysis criteria, and inspection intervals. A forthcoming second volume of the report will describe the proof-of-method and other tests that provided a basis for the guidelines.
