ExxonMobil Pipeline Company works continuously to maintain the integrity, efficiency and reliability of our pipelines and terminal facilities. We rigorously test and analyze our assets to determine maintenance programs, which may range from additional testing and monitoring, to minor repairs to replacement of pipe.
Temporarily reducing a pipeline's operating pressure may provide an additional safety margin until abnormal conditions can be investigated and repaired.
Some localized repairs are made using a steel or composite “sleeve.” The sleeve fully encircles a small area of the pipe that may benefit from additional reinforcement.
Sometimes it is preferable to replace a pipeline or a segment of pipeline. New pipe is typically installed along an existing pipeline or other utility right-of-way to limit surface and environmental disturbance.
