Insulation sets are primarily used in petrochemical applications to electrically isolate two mating flanges. This reduces the likelihood of creating a galvanic cell which would result in corrosion of the flanges and pipework. Insulation sets are also employed to prevent the flow of electrostatic charges and to reduce sparking in hazardous environments.
Each flange insulation set comprises one insulating gasket, one insulation sleeve as well as insulating washers for each bolt. These sets are individually packed and clearly labeled with the flange rating, size, type and material combination.
