FLANGE
INSULATING GASKET KITS
Flanges,
the most common trouble area, need to be sealed properly to prevent
leakage and must also be cathodically insulated to prevent stray
currents which cause undo corrosion and eventual breakdown of the
metal. Advance Products & Systems manufactures and maintains
a supply of quality products and materials which help solve most
flange sealing problems, therefore preventing subsequent corrosion
and saving the integrity of the pipeline.
Advance Flange Insulation Gasket Kits are manufactured according to
ANSI B16.5 specifications up to 24". Above 24", please provide the
specifications of your flange using our convenient worksheet.
Technical assistance is available upon request.
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 insulation. 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 bolts 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. Available in the same materials as the type E gasket.
Standard thickness of 1/8".

INSULATING
SLEEVES AND WASHERS
Insulating sleeves manufactured of high density polyethylene, NEMA
grade LE phenolic, and Mylar are available in a full range of sizes.
Also available are one-piece integral sleeves and washers which are
made of Minton, providing superior compression strength. Integral
sleeves are available in sizes through 1-1/2". A variety of high
temperature sleeves are also stock items. With each insulating washer,
a 1/8" thick S.A.E. electro-plated steel washer is provided to
protect the insulating washer from damage by the nut. Advance flange
insulation sets are available in single washer or double washer kits.
TROJAN
SEALING GASKETS
Trojan gaskets are state-of-the-art in near zero leakage static
sealing. The
elastomer sealing element is encapsulated in the electrically insulated
retainer. The encapsulation of the sealing element permits only
micro-exposure of the seal to hostile environs of fire, chemicals
and corrosive fluids.
Because
of the controlled confinement of the elastomer sealing ring within
the available volume of the groove in the retainer, 92% to 94% filled
volume, a consistent controlled-pressure seal can always be obtained
without tremendous bolt loads. Reduced loads allow for reduced flange
thickness, smaller bolts and smaller circles.
The
cross section of APS’s Trojan Sealing Gasket (A) shows the
elastomer sealing element as it appears before compression between
flanges. This compression causes the seal to effectively fill the
void of the groove and encapsulate, permitting only micro exposure
of the actual seal to hostile elements either from within or without.
QUAD SEAL TROJAN
Four seals on the new Quad-Seal Trojan further insures the integrity
of the sealing capability of an already-proven reliable gasket.
For areas where absolute zero leakage is a must, the Quad-Seal Trojan
works twice as hard.

SPECIAL
APPLICATION
Advance Products and Systems, Inc. is well equipped to make
those special insulation pads and gaskets sometimes required for
odd shaped connections. We can manufacture any configuration or
design needed.
These applications include special closures, vaults, steel boxes,
special connectors, utility and light poles. If
it needs to be sealed…we can be of service.
PACKAGING
Each Advance flange insulation gasket kit is packaged individually
in durable corrugated boxes. Insulating sleeves and washers are
packaged separately and are cushioned within the box to protect
them from damage during shipment. Each set is clearly tagged with
flange size, pressure rating, type of insulating sleeve and whether
it is a single washer or double washer set. A recommended bolt tightening
sequence sheet is provided with each kit.
