Use of dissimilar metallic flanges with a conductive gasket material assisted by a suitable electrolyte sets up a galvanic cell, corroding the anodic metal. It is here that the flange insulating kit gasket or insulation kit comes into use protecting pipeline flange corrosion. These insulation kits are also used to electrically isolate flange joints, preventing flow of electrostatic charges along the pipeline.
