afest and most economical method for transporting fluids (oil and gas) over long distances . Due to this and their efficiency, pipelines have been used for several decades and consequently factors, such as corrosion, fatigue or even erosion increasing the danger of leaks or even bursting, are now critical factors tobe considered. Also it should be pointed out that many pipelines are laid near or beneath roads, railway lines, waterways and even within cities. Therefore it is necessary to have ways to monitor, evaluate and assure the integrity of the pipeline, reducing the risk of leaks and consequently averting environment damage and hazards for the population. For many years, non-destructive tests have been used with efficiency in evaluating the state of the pipelines in the oil industry 。
