Corroded Pipeline Rehabilitation through Pressure-Containing Sleeves Repair Jose Jefferson Morais de Oliveira, Aldo Ramos Santos

Abstract

 Pipelines are safe and reliable facilities for the transportation or transfer of hydrocarbons between borders of geographically distinct operating units. However, defects occur that can affect its integrity during the life of the pipeline. In the present work, the pressure-containing sleeves repair technique is presented as an important alternative for the rehabilitation of corroded pipes. Special attention will be directed to the two most important caution for a successful repair by in-service welding on a pipeline that has had an extensive region of severe external corrosion. They are: the risk of hydrogen-induced cracking (HIC) and the risk of burn through (or burnout) pipeline wall.
