Camprofile Gaskets

Teadit Camprofile gaskets have the following characteristics:

• Operating pressure up to 3,700 psi (250 bar).• Maximum temperature up to 850 F (4550 C).• Wide range of service.• Less susceptible to flange imperfections than conventional flat

metal gaskets. The thin Flexible Graphite or Expanded PTFE core fills up the flange irregularities and prevents the serrated finish from damaging the flanges.

introductionTeadit® Camprofile gaskets offer outstanding flexibility and recovery, assuring seal integrity under pressure and temperature fluctuations, flange rotation, bolt stress re-laxation and creep.Teadit® Camprofile gaskets are used by the chemical and petrochemical industry, as well as in power stations and refineries, on both standard pipework and special applica-tions, e.g. shell and tube heat exchangers, etc. Camprofile gaskets are constructed from a precision serrated metallic core with soft facing materials - flexible graphite or ex-panded PTFE - bonded to either side.Depending on the kind of metal used, TEADIT® Camprofile gaskets can be used for all media from pH 0 to 14.

Designed to be used in most male/female and tongue and groove flanges in heat exchangers.

Camprofiles Gaskets Styles

The core material should be chemically and ther-mally compatible with the fluid to be sealed. If possible the core metal should be the same as used to manufacture the flanges to avoid corro-sion or differential Thermal Expansion.

For Metallic Core:

For Sealing Face:

The most widely used covering material is Graflex® Flexible Graphite. For operational conditions where the Flexible Graphite is not recommended the 24BB Expanded PTFE tape is used. The chart below shows the Temperature and Pres-sure limits for the cover materials.

The Pressure and Temperature range is related to the range of each component. The Service Range is the combination of the limit for the metal and covering limits. For example a Teadit Camprofile Style 942 with a Carbon Steel core and Graflex® covering has the following limits:

Maximum pressure: 5 000 psi (345 bar)

Temperature range: -40 F to 850 F (-400 C to 4550 C)

Style 942

Style 946Designed to be used in RF or FF faced flanges like ASME B16.5 or ASME B16.47.The loose fitting outer ring allow the thermal expansion of the serrated core.
