Cathodic Protection

Cathodic Protection Annual Survey - Working to ensure the safety of pipeline infrastructure

The environmental and societal impact of infrastructure failure is a primary consideration for today’s pipeline operators. This is why since 1950, Corrosion Service has focused on providing corrosion prevention design, engineering, supply and field services to the pipeline industry in Canada and the United States of America.

Cathodic protection is the most common electrochemical technique used to prevent corrosion on buried metallic pipelines where the applied coating has failed or been damaged exposing bare pipeline metal to the soil. Protection is accomplished by applying a direct current to the surface of the metal, which causes the electrochemical potential of the structure to shift from a corroding state to a polarised and non-corroding state.

Our team and the services that we offer

All pipeline systems are different, and whether the project is new build, rehabilitation, or routine maintenance, our talented team of industry professionals is empowered to understand the unique characteristics of every enquiry. This is important because as an organization, Corrosion Service strives to provide the extremely high level of support and partnership necessary in order to create the customized solutions that our clients require on a daily basis.
