Pipelines are subjected to risks that can cause damage to them. These risks are such as internal corrosion due to corrosive fluids, erosion caused by the presence of the solid particles in the flowing fluid, external corrosion, and vandalism of pipes to the external surface of the pipe. In a case of damage and leakage in the pipeline, in addition to the large loss in the product and significant economic loss, it also causes environmental pollution. Therefore, identifying pipeline repair methods and knowing the condition in which each one is applicable is important. From the first day of using pipelines until now, many methods have been used for repairing pipeline defects. While all kinds of defects were always the same, repair methods have been continuously improving to reduce the time, cost and increasing safety and operational certainty. The impact rate of each of these varies according to the parameters such as type of damage, working environment (land and sea), working pressure and temperature, pipe length, fluid, etc. In this project the various methods of detecting pipeline defects, types of pipeline repair and required equipment have been reviewed.
