  • Buried pipe examining method
    Patent number: 7690258
    Abstract: An impact elastic wave test is conducted to measure propagating waves in a pipe to be examined, a frequency spectrum of the propagating waves is analyzed, and at least a spectral area value in a first frequency region and a spectral area value in a second frequency region of the frequency spectrum are evaluated, thereby determining a type of a deteriorated state of the buried pipe.
    Type: Grant
