Insulation joints are used on pipelines to provide electrical isolation to prevent corrosion. They provide current dispersion on cathodic protection systems. They provide electrical isolation between the pipeline section and adjacent structures and pipelines.
What is the purpose of a monolithic insulation joint?
The purpose of installing insulated joints on gas and oil pipelines is to ensure electrical isolation between sections of the pipeline and to prevent harmful electrochemical interactions between the sections. Insulation joints are also used to ensure effective current dispersion on cathodic protection systems.
