Pipe Cracks Detection Methods – A Review

Abstract

A comparison between the most important methods for crack detection during external inspection of the pipes is presented. It is meant to choose the best suited one for robotic devices, aimed to perform the pipelines monitoring, because they are often under the action of the environmental stress factors, like high-temperature variation, especially met in the Middle East countries. As a native from the Republic of Iraq, the first author currently works at development of a robot for external inspection of pipes, within his PhD thesis, in order to provide full care to the pipelines, because they are non-replaceable. This way, their performance and reliability can improved and the production stopping is prevented.
