PULSED EDDY CURRENT TESTING OF A CARBON STEEL PIPE'S WALL-THINNING

Wall-thinning management is of significant importance to the normal operation of piping systems. During long periods of service, corrosion may occur on the inner or outer sides of carbon steel pipes used for transportation and distribution in power plants, and the resultant wall-thinning may cause huge economic loss. Presently, the available nondestructive evaluation (NDE) or monitoring methods are insufficientl
