Details
Long-range guided wave pipe inspection has been a successfully-implemented technique for screening long and/or inaccessible sections of pipes for several decades. However, guided wave testing (GWT), as traditionally implemented with conventional piezoelectric pipe inspection systems, truly excels on longer sections of pipe and screening for relatively severe corrosion. Conventional GWT has significant limitations with regard to shorter and more complex sections of piping and for detecting smaller defects such as small, highly-isolated pitting and stress corrosion cracking. Magnetostrictive (MS) guided wave pipe inspection is an increasingly popular alternative to piezoelectric GWT systems and can open up new inspection opportunities. While MS GWT is possible for a full range of pipe sizes and in frequencies ranging from 20 kHz to over 200 kHz, the focus of this discussion will be higher-frequency applications (>100 kHz) for smaller piping that would be impractical using conventional piezoelectric GWT methods. Due to a much smaller dead zone (typically 20-40 cm as opposed to 1-2 m) and much higher sensitivity (typically <1% CSA as opposed to 3-5% CSA), MS GWT technology can be applied to single sections of in-plant pipework, flanged pipe, and piping requiring higher sensitivity screening for damage mechanisms like SCC, MIC, and CUPS. Several examples of successful field applications of MS GWT will be discussed, including SCC detection in stainless steel piping, highly-isolated pitting in boiler tubes and superheaters, and air-soil interface corrosion in gas distribution jumpers.
