Recent advances in evaluating composite repair technology used to repair transmission pipelines

摘要

FOR THE BETTER part of the past 20 years, composite materials have been used to repair high pressurentransmission pipelines. Initial efforts focused on repairing corrosion; however, as confidence in compositenrepair technology improved the pipeline industry showed greater interest in expanding its usage to repair othernanomalies. The repair of dents and mechanical damage was evaluated through research efforts and the resultsnshowed significant promise. The reinforcement of other features such as wrinkle bends, branch connections,nand corrosion in bends have also been evaluated.nIn this paper the author provides results and insights associated with several extensive research programmesncurrently being sponsored by the pipeline industry and numerous composite repair manufacturers. The ongoingnfocus of these efforts has been to demonstrate to industry the capabilities that composite repair systems have tonprovide long-term reinforcement to damaged pipelines.
