High Temp Gasket Material
Proper selection of gasket material is critical in any application. To achieve a “tight joint” or “seal”, the surface finish, bolt load and environment are all taken into consideration. The environment alone can attack and either corrode or erode that connection. Excessive high temperatures play a leading role in this evaluation. Mechanical and chemical properties are highly temperature dependent. Physical characteristics such as oxidation and resilience are determined by temperature. High temp gasket materials listed below are designed to perform in conditions involving combustible fluids and elevated temperatures:
| Continuous Operating Temp | Media Resistance | Applications | |
|
Flexible Graphite |
+875°F |
Acids, Alkalis, Salt |
chemical & petrochemical refineries; industrial fluid sealing; steam service; thermal, electronic and electrochemical applications |
|
Woven Stainless Steel with Graphite Filler |
+1800°F | Water | chemical & oil refineries; coal, gas, hydro & nuclear power plants; industrial sealing |
|
Fluorosilicone |
+400°F | Fuels, Solvents, Ozone | |
|
Compressed Non-Asbestos (styles 5500, 9800, 9850, 9900, ST-706) |
+750°F | Steam, Oils, Grease, Heat Transfer Fluids, Inert Gases, Most Refrigerants | power generation; chemical & hydrocarbon processing |
|
