Camprofile Style 942 and 946Excellent Results in Critical Applications

Description and Applications

Teadit® Camprofile gaskets offer outstanding flexibility, assuring seal integrity under pressure and temperature fluctuations, flange rotation, bolt stress relaxation 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 applications, 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 expanded 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.

Materials

The core material should be chemically and thermally compatible with the fluid to be sealed. If possible, the core metal should be the same as used to manufacture the flanges to avoid corrosion or differential Thermal Expansion.

Facing

The most widely used covering material is Flexible Graphite. For operational conditions where Flexible Graphite is not recommended Expanded PTFE is used.

The chart below shows the Temperature and Pressure limits for the cover materials.

Facing Materials Temperature and Pressure Limits

Material	Temperature ºF (ºC)		Pressure psi (bar)
Material	min	max	max
Standard Flexible Graphite	-400 (-240)	840 (450)	5000 (345)
High Temperature Flexible Graphite	-400 (-240)	1200 (650)	5000 (345)
Mica Paper	-58 (-50)	1830(1000)	725 (50)
24BB ePTFE	-400 (-240)	500 (260)	1500 (100)

For oxidizing atmospheres the temperature limit for Graphite is 842°F (450°C).

Pressure and Temperature Limits

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 facing limits. For example, a Teadit® Camprofile Style 942 with Carbon Steel core and Standard Flexible Graphite facing has the following limits:

Maximum Pressure:

5000 psi (345bar).

-400ºF to 842ºF (-240ºC to 450ºC)
