WebbThree design current densities are given: initial, final, and average. Initial This is the current density required to effect polarization of the initially exposed bare steel surface. It assumes some atmospheric rusting and/or millscale. The initial current density is higher because of lack of calcareous scales (cathodic chalks). WebbIn congested areas, the stray current can move on and off of multiple pipelines before returning to the source line. In other cases, the current can flow through a layer of low resistance soil to return to the source. Another factor influencing where the current discharges is the coating of the pipeline.
