Selection of materials for valve seat packing and gaskets
Thread Content
When selecting the material for valve seat packing and gaskets, should the design temperature be taken into consideration??? Or only the operating temperature?
It is necessary to consider the design temperature as well as the operating temperature.
The choice of filler is related to temperature; gaskets are related to both temperature and pressure
If you don’t understand anything, don’t take on tasks; let the pipeline specialists handle the gaskets.
Let the valve manufacturers handle these matters.
It is related to the medium’s temperature, pressure, as well as its properties (corrosivity, toxicity)
Of course, otherwise try using rubber instead of graphite
Comprehensive consideration: the chemical properties of the medium, temperature, and pressure all need to be taken into account! Also, regarding the operating temperature and design temperature mentioned by the original poster, is there a large difference between the difficulty levels?
