KLINGERSIL C-4106 Excellent conformity with flange surfaces at low surface load Basis Synthetic fibres and cork, bound with NBR. Special high-pressure gasket for a wide range of industrial applications, also suitable for use with low bolt loads. 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 200°C is measured. The indicated thickness decrease at 200°C refers to the thickness obtained after loading at 23°C. *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. KLINGERSIL C-4106 Technical data 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. 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 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.

The exacting demands made on the tightness of gasket materials (e.g. Tightness class L0.01) mean that with increasing internal pressure higher surface pressures must be applied to the gasket. It must be shown that the flange joint will tolerate the demands made on it without being mechanically overloaded. Furthermore, the surface pressure applied to create the seal should never fall below the required minimum value since this will reduce the life of the gasket. Highly stressed, but not overstressed gaskets have a longer life than understressed gaskets. If the gasket fitted will be subjected to non-static loading, or will suffer stress fluctuations during discontinuous operation, it is advisable to choose a gasket which is not prone to embrittlement with increasing temperature (e.g. KLINGER ®graphite laminate or KLINGER ®top-chem), especially for steam and/or water applications. For discontinuous operations in water and/or steam applications, we recommend as a general guide a surface pressure of about 30 MPa. In such cases the gasket should be as thin as is practicable. Rings and other finished gaskets These gaskets are available in any size and corresponding sheet thicknesses. Function and durability The performance and life of KLINGER ®gaskets depend in large measure on proper storage and fitting, factors beyond the manufactor’s control. We can, however, vouch for the excellent quality of our products. With this in mind, please also observe our installation instructions. For reasons of safety, we advise against the re-use of gaskets.
