When an electric utility in the Southeastern United States sought to protect above ground natural gas pipeline against corrosion, the goal was to cost effectively do so while minimizing downtime and environmental impact.
Yet in the power and petrochemical industries, protecting above ground pipeline from corrosion can be a challenge, particularly when the pipeline carries a cooled compressed gas that draws moisture out of a hot or humid external environment. This causes in use pipeline to continuously drip water, or “sweat”, making adhering a protective coating to the exterior of the pipeline virtually impossible without shutting down the line.
