1. GENERAL INFORMATION
Graphite Laminate Klinger graphite laminate is made from expanded graphite layers which are either glued onto plain sheet metal or rolled onto tanged sheet metal. A homogeneous graphite laminate is obtained by sticking homogenous graphite foils together. The adhesive layer is invoked by means of a controlled process which allows• the volume of adhesive to remain less than 1 % of the graphite volume• an even distribution of the adhesive to be guaranteedThe advantage of this method is that the excellent properties of flexible graphite are retained. As only a low quantity of adhesive is used, the exceptional chemical and thermal resistance of the graphite is not affected.
Properties of graphiteGraphite is characterised by a number of peculiarities, such as, for example:• Temperature resistance from – 200 °C to + 450 °C (or higher in an inert atmosphere)• Exceptional micro-sealing• Exceptional resistance to temperature fluctuations• High thermal conductivity on level ground• No heat or cold transfer, either under pressure or temperature load• Flexibility in the whole temperature range• No swelling or shrinking under the influence of agents• Unlimited shelf life• Easy manipulation• No risk to health
Non-stick coatingIn order to prevent the gasket material from sticking to the flange surface (even at high tempera-tures), the graphite surface can be given a non-stick coating at the customer‘s request. With this process step, it is a matter of coating the graphite surface and not impregnation.
Chemical resistanceGraphite is resistant to almost all agents such as acids, alkalis, solvents, fats, oils, gas, vapour and water. Exceptions to this are strong oxidising agents such as concentrated nitric acid, potassium chlorate, permanganate solutions and chloric acid. Details can be found in the resistance table (Item 9). The resistance of the fillers used are also to be taken into consideration!
Shelf-lifeAs a rule, storage temperature, exposure to light, etc. do not have any influence on the shelf-life of graphite laminates. However, the following conditions for proper storage should be adhered to in order to achieve shelf-lives of > 10 years:• Temperature range – 20 °C to + 50 °C• Clean and dry air (no particles of dirt, no aggressive gases or vapours)• Protection from damages• Store flat goods horizontally

Usage parametersBecause of the high requirements which are placed on the safety of sealing joints and the demands which apply nowadays for the utmost imperviousness, it is necessary to choose and fit the right gasket with the corresponding know-how.The adjustment to the unevenness of the sealing surface is dependent on the compressibility of the gasket as well as the surface texture of the sealing surface and the surface contact pressure.When choosing the material, it must be ensured that the agent resistance of the gasket material is also specified under operating conditions. As a rule, well compressed gaskets are more resistant than slightly compressed gaskets.The overall properties regarding strength and statics are determined by the whole gasket system. Subject to the high requirements of the imperviousness of flange joints, high surface contact pres-sures must be invoked on the gasket with increasing internal pressure. For such operating condi-tions, it must be checked whether this flanged joint is also able to withstand this load without being mechanically overloaded. So that the sealing joint is impermeable, a set minimum surface contact pressure is required. Furthermore, it is exceptionally important for the life span of the gasket that the required minimum surface contact pressure of the gasket is never fallen short of when the gas-ket is in operation. Higher compressed, but not over compressed, gaskets have a longer life span than slightly compressed gaskets. It cannot however be guaranteed that the incorporated gasket is exclusively statically loaded or, in the case that voltage fluctuations are to be expected during dis-continuous operation, then special gasket materials which do not get brittle at high temperatures are used for water / vapour applications.
For gaskets which are used in the discontinuous operation of water-vapour circuits, a minimum surface contact pressure during operation of 30MPa is recommended as a general rule. In such cases, the gasket should be as thin as is both technically possible and reasonable.The imperviousness is dependent on, amongst other things, the surface contact pressure invoked during installation and which remains during operation. A properly chosen and installed gasket will have a long life span. The multiple usage of gaskets is advised against for safety reasons.The maximum permissible surface contact pressure of the gasket material subject to pressure, temperature and gasket thickness must not be exceeded. The sealing joint remains impervious if the surface contact pressure during operation is higher than the required minimum surface contact pressure and the maximum permissible surface contact pressure σBO of the gasket is not exceeded.A generally binding rule for determining the required gasket thickness does not exist. A thickness of 2 mm is usually sufficient; thinner gaskets permit higher surface contact pressures.

Gasket parameter Qmin(L)
The gasket parameter Qmin(L) is defined in DIN EN 13555 as the minimum required surface contact pressure on the gasket when being ins-talled at room temperature so that by adjusting the gasket to the roughness of the flange gasket surfaces and sealing the internal leakage paths, the required tightness class L for the specified internal pressure is achieved.
Gasket parameter QSmin(L)
The gasket parameter QSmin(L) is defined in DIN EN 13555 as the minimum required surface contact pressure under operating conditions, this means following pressure relief in opera-tion at the operating temperature so that the required tightness class L for the specified in-ternal pressure is maintained.
Gasket parameter QSmax
In DIN EN 13555, the gasket parameter QSmax is defined as the maximum surface contact pressure with which the gasket can be loaded at the specified temperature without the gas-ket collapsing or failure occurring as a result of compressive strain.
Gasket parameter PQR
This characteristic is defined as a factor for ta-king into consideration the relaxation influence (settling properties, thickness reduction) on the gasket load after the screws are tightened and the long-term effect of the operating tem-peratures.
Secant modulus EG
Secant modulus of the gasket (pressure relief) in [MPa].

8.1 Definitions
σVU/0.1 Minimum surface contact pressure for achieving leakage class L0.1 (in accordance with DIN 28090-1)
σBU Minimum surface contact pressure during operation, whereby σBU is the product of operating pressure p and the sealing factor m for the test and operating state (σBU = p . m)
σVO Maximum permissible surface contact pressure at RT
σBO, 300°C Maximum permissible surface contact pressure during operation
m σBU / pi
m-factor Similar to m, however defined according to ASTM and therefore a different numerical value
y-factor Minimum surface contact pressure in MPa
k0 in mm, parameter of the effective width of a gasket
k1 in mm, empirical parameter of a fictive gasket width
KD in N/mm2, deformation resistance of the gasket material
εKSW Compression and compressibility under a surface contact pressure of 35 N/mm2
εKRW Springback following a pressure relief of 35 N/mm2 on 1 N/mm2
εWSW Creep of the gasket under a surface contact pressure of 50 N/mm2 at 300 °C after 16 h
εWRW Springback following a pressure relief of 50 N/mm2 on 1N/mm2
The percentage thickness changes of εKSW, εKRW, εWSW und εWRW relate to the starting thickness of the gasket.
The formulae for calculating the gasket parameters in accordance with AD data sheet B7 are:k0 . KD = εVU . bD
k1 = m . bD

8.2 Homogeneous graphite foil
Graphite foil, manufactured from natural graphite, is a homogeneous material with no added bon-ding agents. It has a long usage time in comparison to other gasket materials and does not exhibit any noteworthy change in properties. In order to increase the flexible graphite‘s resistance to oxi-dation and corrosion, inhibitors can be used. Furthermore, graphite foils can be given a non-stick surface in order to prevent the gasket material from sticking to the flanged joint.
