Day in and out, piping circuits can be found in petrochemical, refinery, and energy facilities carrying high-pressure, high-temperature fluids such as hydrocarbons and steam to safely and efficiently perform various processes like distilling crude or driving turbines. The harsh environmental conditions these circuits operate under introduce damage mechanisms such as corrosion/erosion or cracks which can result in a catastrophic release of process fluids. For example, naphthenic acid accelerated sulfidation corrosion can cause uniform wall loss from as low as approximately 180 degrees Celsius (356 degrees Fahrenheit) which is difficult to predict, costly to repair, and has previously caused calamitous ruptures in piping, tubing, pressure vessels, and other refinery assets. Non-Intrusive Inspection (NII) and Non-Destructive Testing (NDT) actions can help support the safe fitness-for-service (FSS) of these critical piping circuits.
