  • Method and apparatus for determining the health and remaining service life of austenitic steel reformer tubes and the like
    Patent number: 10060882
    Abstract: Testing methods and apparatus for testing the health of steel tubes used in reformers and other tubes and pipes used in other high temperature applications are provided. The method includes the steps of transmitting two sinusoidal electromagnetic signals, each having a different frequency F1 and F2, into the reformer tube, receiving a response signal, and analyzing the received response signal's intermodulation frequencies to determine the state of the steel reformer tube.
    Type: Grant
