Line Current

Last updated: April 22, 2016

What Does Line Current Mean?

Line current is the measured amount of direct current flowing in a pipeline. It is an indicator of the degree of reactivity and corrosion experienced on the pipeline’s surface.


Corrosionpedia Explains Line Current

The line current voltage and the composite material of a pipeline can jointly be used to determine the degree of corrosion present in a pipeline. A larger current indicates a greater flow of electrons and more corrosion depending on the measured relative voltage and the documented reactivity profile of the pipeline’s metal.
