Over the last decade, pipeline owners have begun widespread use of fiber-reinforced polymer (FRP) composites, as a strengthening and repair technique. This paper aims to provide an overview on the work done in the field of non-metallic bonded repair of pipes. Reinforcement and repair of components using composite patches can be used for cracked piping to reduce the stress intensity at the crack-tip. Several researches have covered experimental investigation as well as finite element analysis to evaluate the effects of composite patch on the behavior of cracked pipes. Some of the advantages of the composite patch repair technique over classical methods, such as plate bolting/welding, are its better corrosion characteristics and its fatigue performance. Additionally, adhesively bonded composite patches are more structurally efficient than traditional repairs. For this purpose, a review of the composite patch technique is addressed, and many related research works are presented.
