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.
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
*Gaskets according to DIN 2690 are only standardised up to PN 40 (1) If your operating temperatures
and pressures are within this ”open”
field, a technical examination is
always necessary.
(2) If your operating temperatures
and pressures are within this field a
technical examination is
recommended.
(3) If your operating temperatures
and pressures fall within this field, a
technical examination is normally
unnecessary.
 
The three fields of decision do not indicate limits for the use of our material. They indicate a
way to select the right gasket material.
