Insulation sets are often used in petrochemical applications to electrically isolate two mating flanges to reduce the likelihood of creating a galvanic cell which would result in corrosion of the flanges and pipework.
Insulation sets are also used to prevent the flow of electrostatic charge to reduce sparking in hazardous environments.
Insulation sets are generally supplied in kit form comprising an insulating gasket, two insulation and two steel washers and one insulating sleeve per bolt.
