Nondestructive evaluation of ferritic piping for erosion-corrosion: Topical report

Technical Report ·
OSTI ID:6259520

This report was generated to assist utilities in their inspection programs to detect wall thinning caused by erosion/corrosion in nuclear and fossil power plant piping. Included is a logical approach or ''Road Map'' to step utilities through an inspection program. This report provides guidance on selection of examination techniques for specific plant situations, discusses the capabilities of various nondestructive examination (NDE) techniques (both currently available as well as those under development), describes the specific essential variables associated with each NDE technique, and gives suggestions for additional detailed examinations if erosion/corrosion is detected. Ultrasonic, radiographic, and visual examination methods are discussed in detail; other NDE techniques are briefly mentioned. This report addresses NDE considerations only; selection of piping for examination, disposition of findings, and pipe repair or replacement are not within the scope of this work and are discussed briefly only to show their role in the overall inspection program. 17 refs., 66 figs., 3 tabs.
