Development of Guided Wave Examinations of Piping and Tubing Using Magnetostrictive Sensor Technology

摘要

Screening of piping and tubing using long range guided waves have become increasingly attractive over the last decade due to high effectiveness of the technology in finding hidden metal losses. Different types of transduction systems together with the philosophy of long range guided wave UT have been developed and tested using piezoelectric, and EMAT actuators. Practical implementation of the technology helped to recognize the number of the most challenging applications when there is a need for better sensitivity, better inspection range, and better flaw characterization. Establishing of consistent and uniform data interpretation has been recognized as a stand-along challenge. A review of magnetostrictive sensor technology will be given in reference to the new developmental work dedicated to the improvement of the performance of long-range guided waves when applied to piping and tubing components.
