Pipeline Corrosion Protection Using Impressed Current Cathodic Protection
Application ID: 115451
In this example, three parallel pipelines of length 68 km and a horizontal separation distance of 10 m between them are protected against corrosion by an impressed current cathodic protection (ICCP) system using a series of anodes.
Each anode is connected to all three pipelines, demonstrating a one-to-many connection modeled by the Impressed Current Point feature and by Connection Point and External Short point subfeatures of the Edge Electrode feature.
The model considers two layers of soil of different electrolyte conductivity. The electrode potential and the total interface current density are plotted along the length of the pipelines to evaluate if they are adequately protected against corrosion.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license.
