Flange Insulation Gasket Kit
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.
Gasket Type:
TYPE E -
Type E gaskets are for full face protection of both flange
faces
TYPE F - Type F are to fit the raised face surface
area of the flanges.
TYPE D - Type D are made to fit the ring grooves on
ring type joint (RTJ) flanges.
SEAL TYPE O - Gasket and O Ring are available in
different materials to maintain constant contact with the
flange face.
How to Order
Specify The Following:
* Specify
Flange Size and Pressure Rating
* Specify
Gasket Type: D, E, or F.
* Specify
Gasket Sealing Element, Sleeve and Washer
Material.
Insulation Gasket Types:
> Type E Gasket;
> Type F Gasket.
Descriptions:
Type E Gasket:
Type "E" 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:
Type "F" Gaskets 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.
Recommended Installation Procedure:
* 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.
* Insert
the bolt with both insulating washers against the flanges followed
by the steel washer and nut.
* Tighten
two diametrically opposite bolts to 30% to total
torque.
* Replace
the two alignment pins with bolts and tighten the remaining bolts
to 30% of the total torque value.
* Tighten
all bolts to 50%, then to 100% of final torque
value.
* Bolts
should be of
sufficient length to extend through the nut approximately
1/4".
