FLANGE INSULATION KITS

Type E Flange Insulation Kit

Pressure Class: 150 to 2500 PSI

Pipe Size: 1/2" through 144"

Our Flange Insulation Kits are made of the highest quality materials designed to provide cathodic protection for the control of corrosion losses. They provide high dielectric strength and are carefully fabricated for proper installation. Full face gaskets have precision located bolt holes and the same outside diameter as the flanges to prevent foreign materials from lodging between the flange faces. Ring gaskets are for use with raised face flanges and it is recommended that the outside of the flanges be taped to prevent foreign material contamination.
