Can silicon-free semi-rigid rubber resist corrosion by 92.5% sulfuric acid?

Thread Content

At our project site, there is a 5m3 sulfuric acid metering tank made of carbon steel, lined with 5 mm thick silicon-free semi-rigid rubber, with a sulfuric acid concentration of 92.5%. Is the designer’s design feasible?

Silicon-free semi-rigid rubber generally does not resist concentrated sulfuric acid, and using it will present problems. If rubber must be used, fluororubber is a good choice.
