Insulation joint is used to break the current flow of an underground pipeline that is equipped with cathodic protection. To protect the underground pipeline from corrosion, cathodic protection is used. An external current is supplied to the pipeline. However, if this current flow continues when the line goes above-ground, it will damage the paint that applied to protect the above-ground pipeline. To avoid this situation, insulation joint is used. It is designed in such a way that it will break the flow of current. Here in the image, you can see the configuration of insulation joint.
