There are over 10 million kilometers of pipes and pipelines around the world that carry hazardous fluids and gases. Fluids include oil, oil products, chemicals such as solvents, caustics, acids, corrosives and combustibles often at high pressure and temperature. These pipes are susceptible to corrosion if they are not protected properly by the environment or the contents. Inspection of pipes is usually mandatory to ascertain their structural integrity as corrosion can lead to failure or rupture of the pipe leading to leakage of hazardous material into the environment or even explosion. Guided wave inspection such as Teletest is a screening technique that is utilised to locate corrosion on pipelines. These commonly use piezoelectric transducers in contact with the pipe surface to induce the ultrasonic wave into the pipe.
