Flange Insulation Gasket Kit

Product Description

Flange Insulation Kits are the most widely used form of controlling losses due to corrosion.
They can be used to control stray electric currents in piping at oil, gas, water, refinery, and chemical plants,
to increase the effectiveness of cathodic protection systems and confine or eliminate electrolytic corrosion.

Descriptions:

Type E Gasket:

 is a full face flange gasket, it's for FF Gasket with same out diameter asthe full face flange and precision cut bolt holes.

It is designed facilitates proper alignment of the gasket during installation.

This assembly minimizes the ingress of conductive foreigh matter between the portions of the flanges, outer side the rase face and reduces the risk of bridging.

Type F Gasket:

 are made to fit the raised face protion of the flang only.

As there are no bolt holes in this F type gaskets, the out diameter of the gasket fit tightly into place assuring a well centered position.

Verify that the installation kits contain the material specified and the contents are not damaged.
*Clean and inspect pipe flange faces and apply lubricant to all threads.
*Install the gasket and align the flanges so the bolt holes will be centered.
*Use alignment pins in two diametrically opposite bolt holes whenever possible to assure proper alignment of flanges and gasket.
*Insert insulating sleeves into the bolt holes taking care not to use force which could damage the sleeve material.
*
 Tighten two diametrically opposite bolts to 30% to total torque.
*
 Tighten all bolts to 50%, then to 100% of final torque value.
* of sufficient length to extend through the nut approximately 1/4".
