Firesafe Gasket for H2SO4 92-98% service
(OP)
What type of firesafe certified gaskets is possible to use in H2SO4 92-98% service (max 100°C)? I asked about Grafoil gasket but the chemical compatibility table of this material show it like non recommended in H2SO4 service over 95%
Could you help me?
Thanks

Ceramic-fibre-filled or Flexitallic "Thermiculite"-filled spiral wound gaskets would be worth considering.

One proven firesafe gasket for sulfuric acid alky systems is Inpherno style (PTFE and Graphite filler) spiral wound gaskets.

I recived from Klinger the firesafe certification relative to their Topchem 2000 gasket type.
The certification recived is about a test DN50 PN40 30 bar TOPCHEM 2000 GASKET (107x60x1,5mm) based on the "specification for fire test for Valves" according to API specification 6FA confirmed by TUV osterreich department (document WP547/MK/BE 27/03/96).
