Corrosion leads to degradation and mechanical decay of metallic materials. The thickness variation caused by corrosion in oil pipelines can change heat flow condition, resulting in fluctuation of surface temperature detectable by thermal infrared sensors. The current state-of-the-art in this field shows mainly two methods have been used so far. The first one employs instantaneous heating, under controlled time frequency, in plates with milling notches of defined geometry. Among the relevant results of this method is the determination of the "visibility limit" of defects. The second method has carried out by instantaneously (at single thermal flash) heating sample pipes, highly corroded inside. The method has resulted in defining an approximate experimental algorithm to quantify the defect.
