Non-destructive measurement of pipe wall thickness
CA 2347567 A1
The average wall thickness of a pipe carrying a fluid is determined by sensing disturbances in the pipe at two spaced locations, determining the propagation velocity of coupled propagation mode signals at low frequencies resulting from the disturbances, and calculating the average pipe wall thickness between the two locations from the propagation velocity and known constants for the pipe and fluid.
