Pipe wall thinning caused by FAC (Flow Accelerated Corrosion) and LDI (Liquid Droplet Impingement)is managed through the measurement of pipe wall using UT (Ultrasonic Test) and the replacement of thinning element until reaching allowable limit in order to prevent pipe failure in Japan. Minimum wall thickness of design codes is applied to the allowable limit of pipe wall thinning management. On the other hand, the thinning area is localized in pipe wall caused by FAC and LDI, so the integr ity of piping sys...
