What type of gaskets are used for the oxidation furnace body in silver-process formaldehyde production?
Thread Content
As the title suggests, are there any experts in the production of formaldehyde using the silver method? Are your oxidation furnaces connected using multiple flanges? What material is used for the gaskets used during handover? Are there gaskets made of woven tetrafluoroethylene?

Yes, the PTFE gasket won’t work.
Metal-wound graphite gaskets are generally used
