Graphite Raschig Ring is a kind of graphite material and is equal to the diameter of the high temperature resistance, acid and strong acid and alkali chemical packing. Using a high temperature of 200 DEG C, the ability of 48% concentration following hydrofluoric acid has good corrosion resistance to sulfuric acid, nitric acid, potassium hydroxide, sodium hydroxide and strong acid substances and most organic salts, solvents etc.. Its performance indicators (especially strength and hardness) are better than similar specifications of imported products.

Graphite Raschig Ring has the advantages of low pressure drop, high flux, liquid distribution uniformity, high mass transfer efficiency, absorption or for gas washing of tail gas, separation etc.. It has replaced a large number of ferrous metals and non-ferrous metals, is a kind of non - metallic materials with excellent corrosion resistance.
