Technical data
 

Important points to be observed
With heightened awareness of safety and environmental issues, reducing leaks from flanged assemblies has
become a major priority for industry. It is therefore important for companies who use gaskets to choose the
correct material for the job and install and maintain it correctly to ensure optimum performance.
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.
If the gasket is to be subjected to non-static loading and stress fluctuations due to temperature and
pressure cycling, it is advisable to select a gasket material which is less prone to embrittlement
with increasing temperatures (e.g. KLINGERgraphite laminate, KLINGERtop-chem or KLINGERtop-sil).

In cyclic loading conditions we recommend a minimum surface stress of 30 MPa and that the gasket
should be as thin as is practicable. For safety reasons never re-use gaskets.

Function and durability
The performance and service 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.
