The many, varied demands placed on gaskets A common perception is that the suitability of a gasket for any given application depends upon the maximum temperature and pressure conditions. This is not the case. Maximum temperature and pressure values alone can not define a material’s suitability for an application. These limits are dependent upon a multiplicity of factors as shown in the diagram opposite. It is always advisable to consider these factors when selecting a material for a given application. Selecting gaskets with pT diagrams The Klinger pT diagram provides guidelines for determining...

Maximum permissible surface pressure σBO under operating conditions acc. DIN 28090 – 1 The maximum surface pressure under operating conditions is the maximum allowable surface pressure on the effective gasket area under service conditions that can be applied to the gasket before unacceptable relaxation of the flanged joint occurs and/or the gaskets are destroyed. 500 Min. surface pressure σVU for tightness classes L = 1.0, L = 0.1 and L = 0.01 in accordance to DIN 28090 The minimum surface pressure is the minimum surface pressure that should be applied to the gasket to achieve the necessary tightness...

KLINGERSIL C-4400 Flanged joint integrity A flanged joint will remain tight as long as the surface pressure in service is higher than the minimum surface pressure required to achieve the necessary levels of tightness but is lower than the maximum permissible surface pressure.But increasingly high demands on the tightness requirements for flanged joints (e.g. Tightness class L 0.1 in accordance with DIN 28090) necessitate the application of high loads on the gasket material in order to meet these stringent requirements.

KLINGERSIL C-4400 Installation instructions ® The following guidelines are designed to ensure the optimum performance of our gasket materials: 5. Gasket Dimensions Ensure gasket dimensions are correct. The gasket should not intrude into the bore of the pipework and should be installed centrally. 8. Retightening Provided that the above guidelines are followed retightening of the gasket after joint assembly should 1. Choosing the gasket not be necessary. There are many factors which must If retightening is considered necessary, then this should only be be taken into account when choosing 6. Bolting...
