KLINGERSIL C-4509 For highest thermal and mechanical stresses Basis Carbon fibres and special high-temperature resistant additives, bound with NBR. Very high stress capability due to expanded-metal reinforcement of galvanised 1.1203, suitable for high bolt loads. Particularly efficient in the higher pressure and temperature ranges and with load fluctuations because of the high-tech material used. In addition, the expanded-metal reinforcement provides for blow-out protection in case of damage. Main fields of application: strong alkaline fluids and steam. The basic material KLINGERSIL® C-4500 is a Fire Safe grade in accordance with API 607. On request, KLINGERSIL® C-4509 is also available in the stainless-steel reinforced version KLINGERSIL® C-4509-L. The technical data are the same. The specific technical advantages of the material are guaranteed up to a thickness of 1.5 mm. Klinger cold/hot compression With this test method developed by Klinger you can evaluate the cold/hot compression of a gasket in cold and hot condition. Unlike the method acc. to DIN 52913 and BS 7531, the surface load is kept constant during the complete test so that the gasket is exposed to much tougher conditions. The thickness decrease at an ambient temperature of 23°C and at heating up to 300°C is measured. The indicated thickness decrease at 300°C refers to the thickness obtained after loading at 23°C. Premium quality high pressure gasket suitable for a wide range of industrial applications. *Gaskets according to DIN 2690 are only standardised up to PN 40 and gasket thickness 2 mm. 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. is not infallible: it serves as a rough guide for the end user who often has only the operating temperatures and pressures to go on. Additional stresses such as greatly fluctuating load may significantly affect whether a gasket is suitable for the application. Resistance to media must be taken into account in every case. 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. case. The maximum temperatures and pressures at which gaskets may be used are influenced by a large number of factors. Therefore a definite statement of these values for gasket material is not possible. So why does Klinger provide pT diagrams? For the reasons given the pT diagram
