Insulation sets are used to limit corrosion in pipeline systems. Where dissimilar metals are present, the sets remove the possibility of the system acting as a galvanic cell and reduce the rust of galvanic corrosion of the pipework.
Insulation sets are also used to isolation cathodically protected piping systems where they prevent the flow of electro-static charge.
Each flange insulation set comprises one central flat or oval section gasket, one insulation sleeve, two insulating washers and two plated steel washers per bolt. The sets are individually packed and clearly labeled with the flange rating, size, type and material combination.
