High Temp Elastomer
High Temp Elastomer
(OP)
We are trying to source a high temperature elastomer. Is there anything available that can withstand 370 degrees celcius?

RE: High Temp Elastomer
Further investigation has lead me to believe I can offer a woven fiberglass fabric.
The only other condition the material needs to satisfy is the seperation of different metals to avoid galvanic action.

What are the operating conditions and environment
What type of environment is causing you to look for an isolation gasket at your temperature as at this temperature galvanic corrosion would a rarity..
As stated above your temperatures are way and above the elastomeric gasket range. The is the temperature where you would start looking for reinforced gasket material if any pressure is involve
RE: High Temp Elastomer
All the data I have comes from the standard pipe support drawing for a particular pipe shoe. The physical application is very common for us to see, the temperature range is unusual.
The detail drawing was likely copied from a similar pipe shoe used on much cooler lines. The term "elastomer" was copied over with little regard for its appropriate use. The notes describing what the elastomer is supposed to accomplish have led me to believe that a woven fiberglass cloth ("Thermofab") will suffice.
Our company is frequently put into this type of situatuion due to "Copy - Paste" errors. To save time a draftsman will copy the closest detail he can find and modify dimensions or text as required (I've done it myself). Unfortunately draftsmen are not required to understand if certain types of materials are suitable for the new application.
We were lucky in that the client asked us to confirm if we could find material suitable for high temperature. To add to the confusion he incorrectly converted from 370 celcius to 600 farenheit. We referenced 600 F on our offer and someone else caught the discrepancy.
If someone can suggest an alternative to Thermofab I would be happy to hear it in any case.

Here are is he block type insulation used on pipe supports depending on you support configuration. Look around this site as they have a lot pipe support products.
last but not least is a Webinar on pipe supports.
