摘要

A method of testing an austenitic steel reformer tube comprising: providing a sample (1) austenitic steel reformer tube to be tested; choosing one or more test positions in said austenitic steel reformer tube (1); characterized in that it comprises: transmitting two sinusoidal electromagnetic signals, each with a different frequency F1 and F2, to a test position in the austenitic steel reformer tube (1); receiving a response signal from said test position; and analyzing the fundamental and intermodulation frequencies of said received response signal to determine the state of the austenitic steel reformer tube (1) in said test position.
