Flange Insulating Gasket Kits

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 Neoprene face 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"

HIGH TEMPERATURE PRODUCTS
  • GASKETS: NEMA grade G7 and G10, Durabla, Durlon, Lydall, JMRD81
  • SLEEVES: Nomex, NEMA grade G7, G10, Durabla, Durlon
  • WASHERS: NEMA grade G7, G10, Durabla, Durlon

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.
