Flange seal
Thread Content
I’m looking for a sealing material for type A flat welding flanges, in accordance with the standards GB/T3985 – namely, asbestos rubber sheets. Everyone, my flanges are of type A flat welding type; should I use gaskets according to JB/T4705–2000, or asbestos rubber sheets as specified by GB/T3985-2000?

There is no standard, but GB4720－92 specifies the temperature resistance of various asbestos boards; I’m not sure what information you are looking for.
The specific materials to be used are likely related to pressure, temperature, and the properties of the medium. Please describe the specific operating conditions so that others can help analyze them for you.
Boss, the shell-side pressure is 0.25 MPa, and the cooling water flowing through the shell is at 35–45°C. Please help analyze it
The medium is water, with low temperature and pressure; an asbestos sheet from XB150 will suffice
