The pressure/temperature graphs shown are the most current method of determining the suitability of a gasket material in a known environment. However, chemical compatibility must also be considered.
ρT diagram for thickness 2.0 mm:
In area 1 the gasket material is suitable using common installment practices subject to chemical compatibility
In area 2 appropriate measures are necessary for installation of the gasket to ensure maximum performance. Please call or refer to KLINGERexpert for assistance.
In area 3 do not install gaskets in these applications without first referring to KLINGERexpert or contacting KLINGER Thermoseal’s technical support service.
The ability of a gasket to make and maintain a seal depends not only on the style and quality of the gasket material, but also on medium being sealed, the flange design, the amount of pressure applied to the gasket by the bolts and how the gasket is assembled onto the flanges and tightened. These factors are beyond the manufacturer’s control. Please take note of our installation manual in TECHNICAL RESOURCES.
