Unformatted text preview: cathodic control. The resulting polarization leads to increased corrosion of the active metal. 2. Effects of Distance. The distance effect is dependent on solution conductivity because the path of current flow is the primary consideration. Dissimilar metals in a galvanic couple that are in close physical proximity usually suffer greater galvanic effects than those that are further apart. If dissimilar pipes are butt welded with the electrolyte flowing through...
