FLANGE INSULATION GASKET KITS

Flanges, the most common trouble area, need to be sealed properly to prevent leakage and must also be cathodically isolated to prevent stray currents which cause undo corrosion and eventual breakdown of the metal. Insulation gasket kits help to solve most flange sealing problems, therefore preventing subsequent corrosion and saving the integrity of the pipeline.

TYPE D
Type D gaskets are specifically designed to fit into the ring groove of ring-type-joint flanges. They are manufactured of a medium weave, fabric-reinforced phenolic material and are sized to ANSI specifications available in basic oval as well as octagonal shape. Also available are BX gaskets with pressure ratings to 15,000 PSI.

TYPE E
Type E is a full-faced gasket with the same outside diameter as the flange and precision cut bolt holes. This design facilitates proper alignment of the gasket during installation and foreign material prevented from shorting the flange isolation. Type E gaskets are available in plain face or Nitrile faced phenolic, as well as a variety of high temperature materials. Standard thickness of 1/8″.

TYPE F
Type F gaskets are made to fit the raised face portion of the flange only. As there are no bolt holes in the F gasket, the inside diameter of the bolt hole circle is slightly smaller than the outside diameter of the gasket, assuring an exact, automatic positioning of the gasket. Type F gaskets are available in the same materials as the type E gasket. Standard thickness of 1/8″.
