Hydrofluoric Acid Resistance Graphite Raschig Ring Carbon Raschig Ring for Desulfurization Tower

The product not only retains the high temperature resistance and high corrosion resistance of natural graphite, but also can withstand acid with concentration below 48%, and has good corrosion resistance to nitric acid, sulfuric acid, potassium hydroxide, sodium hydroxide strong acid and alkali substances, most organic salts, solvents, etc. At the same time, the use temperature is up to 500 ℃, and can withstand neutron flow β Ray and γ Long term irradiation of γ – rays. Its thermal conductivity is more than twice that of ordinary carbon steel, its thermal expansion coefficient is small, and its temperature change resistance is good It replaces a large number of ferrous metals and a variety of non-ferrous metals, and is a non-metallic material with excellent corrosion resistance The products are mainly used as packing in propane stripper and acid containing gas absorber, as well as in strong corrosion devices in ammonium based, reforming, petroleum, chemical and other industries
