In the single-jacketed overlap construction the maximum flange width is approximately 1/4". this type of gasket is used when total enclosure of the soft filler material is required and when the flange width makes it impractical to use a double-jacketed gasket.

The majority of applications for single-jacketed gaskets are normally 1/4" or less in radial width. This type of gasket is widely used in air tool applications and engine applications where space is limited, gasket seating surfaces are narrow and relatively low compressive forces are available for seating the gasket.

Double-jacketed gaskets are probably the most commonly used style of gaskets in heat exchanger applications. They are available in virtually any material that is commercially available in 26-gauge sheet. They are also extensively used in standard flanges where the service is not critical. Since most double-jacketed gaskets are custom made, there is virtually no limit to size, shape or configuration in which these gaskets can be made. In some cases nubbins are provided on heat exchanger designs to provide an intermediate seal. This nubbin is normally 1/64" high by 1/8" wide. Experience has indicated, however, that there is little advantage to this particular design. The primary seal is still dependent on the inner lap of the gasket doing the brute work and the secondary seal, when applicable, would be provided by the outer lap.

The double-jacketed, double-shelled gasket is similar to the double-jacketed gasket except that instead of using a shell and a washer, two shells are used in the fabrication of the gasket. It has the advantage of a double lap at both the I.D. and the O.D. of the gasket, adding greater stability to the gasket. The construction will withstand higher compressive loads. Double-shell gaskets are normally restricted to use in high pressure applications.

Deltaone spiral wound gaskets are available in a variety of styles to suit the particular flange facing being utilized on the flanges.  A winding is made of alternate plies of a metal wire and a soft non-metallic filler. The metal wire in the gasket is preformed into a "chevron" configuration, allowing superior resiliency and self-adjustment when compared to conventional gaskets. The Style W is just a sealing component (winding) only, which is normally used on tongue and groove joints, male and female facings and groove to flat flange facings.

DELTAONE Inhibitor gasket provides corrosion resistance in the most extreme conditions. It combines a HTG filler configuration with highest purity graphite, and a Kammpro inner ring laminated with soft PTFE material. The design of the Inhibitor gasket utilizes the Kammpro inner ring to provide the primary sealing interface. The inner ring material and its covering layer are inert in terms of corrosion through contact with dissimilar materials. This fire safe design incorporates the sealing integrity of highest purity graphite in conjunction with mica on the ID and OD, preventing the entrance of further corrosive conditions to the media.

Flat metal gaskets are best suited for applications such as valve bonnets, ammonia fittings, heat exchangers, hydraulic presses, tongue-and-groove joints. They can be used when compressibility is not required to compensate for flange surface finish, warpage or misalignment and where sufficient clamping force is available to seat the particular metal selected. They must be sealed by the flow of the gasket metal into the imperfections on the gasket seating surfaces of the flange. This requires heavy compressive forces. The hardness of gasket metal must be less than the hardness of the flanges to prevent damage to the gasket seating surface of the flange.

The hardness of the ring should always be less than the hardness of the flanges to prevent flange deformation. Dimensions for API ring joint gaskets and grooves are covered in ASME B16.20 and API6A DELTAONE stocks a wide range of sizes and materials ready for immediate shipment from R11 to R105. Stock materials include large variety of metals.

API ring Joint gaskets come in two basic types, an oval cross section and an octagonal cross section. These basic shapes are used in pressures up to 10,000 DELTAONE. The dimensions are standardized and require specially grooved flanges. The octagonal cross section has a higher sealing efficiency than the oval and would be the preferred gasket. However, only the oval cross section can be used in the old type round bottom groove. The newer flat bottom groove design will accept either the oval or the octagonal cross section. The sealing surfaces on the ring joint grooves must be smoothly finished to 63 micro inches and to be free of objectionable ridges, tool or chatter marks. They seal by an initial line contact or a edging action as the compressive forces are applied.   The hardness of the ring should always be less than the hardness of the flanges to prevent flange deformation.

Kammpro - HTG is recognized as a problem solver for heat exchangers, large vessels and equipment that experience high operating temperature. It utilizes a section of high performance mica/phyllosilicate that protects the graphite and shields it from contact of oxidizers. Kammpro HTG represents the best technology available in regards to torque retention and seal ability at elevated temperatures.

Kammpro Dual Seal mates with leak detection devices incorporated into flanged assemblies used in critical applications, such as lethal service. This highly effective gasket has a primary seal followed towards the outer portion of the sealing area by a relief section with through holes, where the leak detection equipment is mounted. Past this relief section is a secondary sealing area that will maintain the integrity of the bolted joint should the primary seal be compromised and pressure differential is identified.

Kammpro ACHE is specially designed to replace traditional solid metal "washer" type gaskets typically used in air cooled heat exchangers. The design takes advantage of the serrated profile with graphite facing to bite against the finish of the header plate and fill in the voids, creating a superior level of tightness. The Kammpro-ACHE has proven to be a very viable solution to emission concerns found where optimal conditions for metal-to-metal sealing are not realized.
