The easy detection of fouling in duct systems is a persistent problem and remains a relevant demandfor the chemical, oil, food and pharmaceutical industries. This work presents preliminary research results of vibrational hammer excitation for easy to use external non-invasive, non-destructive fouling detection in pipelines and other large scale duct systems. The main goal is the detection of inner pipe layer formation, and thickness estimation of the adsorbed material. Data were taken from the vibration amplitude variation in presence of an inner pipe fouling layer using acoustic accelerometer detection, combined with FE (Finite Elements). The experimental set-up, achievable sensitivity and limitations ofthe method are outlined.
