Flange Insulating Gasket
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.
Flange insulating gasket kits or insulation kits offered by Goodrich Gasket Pvt Ltd comprises of:
Phenolic laminate/neoprene faced Phenolic laminate gasket [Type E & F only] between the flange sealing faces.
Phenolic laminate bolt sleeves.
Two insulating washers per bolt.
Two plated mild steel washers per bolt. [Stainless steel washers available upon request]
