A Review on Various in-pipe Inspection Methods for a Pipeline

In this contemporary world, one of the major mode of transportation for hydrocarbon fluids are pipelines. The pipes should be designed and constructed in order to stay healthy and safe for various environmental conditions and different loading conditions. Pipeline defects and leakage due to failures may cause danger to environment, humans and leads to heavy financial losses. So periodic inspection is a very important procedure and there are many methods available for the leakage detection and localization. These methods are discussed and compare in this paper.
