Basis Mineral Fibres bonded with NBR. Typical Applications Suitable for a wide range of applications including oils, solvents and gases. Excellent conformity with the flanges at low surface loads. Max. temperatures 250°C and max. pressure 40 bar. (The maximum temperatures and pressures are dependent on the thickness of gasket material, flange conditions, bolt loading and service conditions. Since the ability of the gasket material to resist pressure is dependent on the temperature the maximum values do not apply simultaneously.) Gasket for liquids and gaseous media at lower pressures and temperatures and low bolt loads. Good resistance to oils, hydrocarbons, refrigerants and other chemicals. Klinger Hot and Cold Compression Test Method The Klinger Hot Compression Test was developed by Klinger as a method to test the load bearing capabilities of gasket materials under hot and cold conditions. In contrast to the BS 7531 and DIN 52913 tests, the Klinger Compression test maintains a constant gasket stress throughout the entire test. This subjects the gasket to *Gaskets according to DIN 2690 are only standardised up to PN 40 and for a thickness of 2 mm. more severe conditions.

The many and varied demands made on gaskets The successful operation of a gasket depends upon a multiplicity of factors. Many who use static gaskets believe that the values quoted for maximum admissible temperature and maximum operating pressure are inherent properties or characteristics of gaskets and gasket materials. Unfortunately, this is not the case. The maximum temperatures and pressures at which gaskets may be used are influenced by a large number of factors. So why does Klinger provide pT diagrams? For the reasons given the pT diagram is not infallible: it serves as a rough guide for the end user who often has The fields of decision If your operating temperatures and pressures fall within this field, a technical examination is normally unnecessary. If your operating temperatures and pressures are within this field, a technical examination is recommended. If your operating temperatures and pressures are within this “open“ field, a technical examination is always necessary.
