Flange Insulators
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.
ADVANTAGES OF THE TROJAN
- Can be utilized with mismatched flanges
- Can be utilized with misaligned flanges
- Can be used in place of RTJ or BX rings
- Little initial torque required
- No re-torquing required
- Sealing ring cannot be left out
- Seal design tested for high pressures
- Reusable
- Competitive price
- Limited area of seal exposed (long fire life)
- Compensate for pressure fluctuations, compression changes, vibrations, temperature, variations, etc.
- Greatly reduces human error during installation
- Large selection of materials available
- Three to four times the dielectric strength necessary
- Low installation and maintenance costs
- Gaskets through 144"

SPECIAL APPLICATIONAdvance 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.
