Low-energy piping system failures in power-generating facilities are often the result of fouling and corrosion. These degradation mechanisms can affect the capacity of piping for fluid-carrying, the heat transfer rates of heat exchangers, and the structural integrity of piping systems. Steels are not immune to pitting, underdeposit corrosion, and microbiologically influenced corrosion (MIC). Once advanced inspection technique, using an enhanced ultrasonic inspection system coupled with special imaging software, has demonstrated the capability to accurately image and size closed tunneling pits that often form in austenitic stainless steel weldments due to MIC.
