Flange Insulating sealing gaskets are used to solve the sealing and insulating problems of flanges, and to control losses due to corrosion and leakage
of pipelines. They are widely used to seal flanges and control stray electric currents in piping at oil, gas, water, refinery, and chemical plants, to increase
the effectiveness of cathodic protection systems. flange insulating gaskets use a rectangular sealing element enclosed into a unique groove to seal and
isolate all types of flanges. This kind gasket can provide theoretical near zero “m” and “y” factors resulting in effecting a positive seal without excessive
bolt loads required with flat gaskets. Materials such as Teflon and Viton also can be Used as the sealing element, which increases the choice of material.
Type “E” (Full Face) Gaskets have same outside diameter of the flange and precise located bolt holes, this feature will help to automatically center the
gasket, and offer maximum protection against foreign material “shorting-out” the flange.
Type “F” (Ring Type) Gaskets are made to fit within the bolt hole circle of the flange. The O.D. of the gasket extends out to the I.D. of the bolt hole circle
for good protection against foreign material “shorting-out” the flange.
