pT diagrams
The Klinger pT diagram provides guidelines for determining the suitability of a particular gasket material for a specific application based on the operating temperature and pressure only. Always refer to the chemical resistance of the gasket to the fluid.
Temperture: -196 to 260°C
Pressure: up to 140 bar depending on application
1. In area one, the gasket material is normally suitable subject to chemical compatibility.
2. In area two, the gasket materials may be suitable but a technical evaluation is recommended.
3. In area three, do not install the gasket without a technical evaluation.
