Flange Insulation

Flange Isolation Gasket Kits are typically used on offshore installations, seawater environments, chemi­cal installations and oil refinery pipelines where galvanic corrosion protection and electrical insulation is required. 

Constructed of high quality materials that have a high dielectric constant and low water absorption, Flange Isolation Gasket Kits are available in various configurations to suit your requirements.

Each kit contains an insulating gasket, isolating bolt sleeves and washers all correctly sized according to the flange standard – all packed together to ensure safe and correct site assembly.
