Corrosion inhibitor selection for wet pipelines
- Buck (Erwin), Ponca City, OK (United States)
Selection of corrosion inhibitors for wet pipelines is based on laboratory testing and field confirmation. Both the use and selection of corrosion inhibitors are driven by economics. Economics of alternative corrosion protection methods is not treated in this paper, but the economics of proper inhibitor selection are. The key to successful inhibitor selection is careful analysis of pipeline flow conditions and experimental emulation of its corrosive environment. Transportation of inhibitor to the corroding interface must be explicitly considered in the emulation. Standard corrosion rate measurement methods are used to evaluate inhibitors. Inhibitor properties tabulated during evaluation form a core database for continuing quality control.
