This paper describes a material designed to interact specifically with highly corroded and weathered pipe to enable in-place application and refurbishment. -
Internal corrosion has caused ADNOC to suffer loss of containment in oil flowlines in a giant onshore field. This paper describes the successful 5-year field trial program and confirmation that HDPE liner application in carbon steel pipe can be a cost-efficient way to mitigate internal corrosion.
