Graphite Raschig ring is a kind of chemical filler with high temperature resistance, hydrofluoric acid resistance, strong acid and strong alkali. The use temperature is up to 200 ℃, and it can resist hydrofluoric acid below 48% concentration. It has good corrosion resistance to nitric acid, sulfuric acid, potassium hydroxide, sodium hydroxide, strong acid and alkaline substances, and most organic salts and solvents. Its performance indicators (especially strength and hardness) are better than imported products of similar specifications after testing. Its performance indicators (especially strength and hardness) are better than imported products of similar specifications after testing.

● Graphite Rashid ring packing is mainly used in practical applications such as gas absorption, acid gas desorption, washing, and fertilizer production. It is also used as a packing in propane stripping towers and acid-containing gas absorbers. Used in the furnaces and towers of petrochemical equipment for the purification, absorption, condensation, distillation, evaporation, filtration, washing and other industries of highly corrosive materials.

● It has the characteristics of high temperature and pressure resistance, low water absorption and stable chemical properties. Can withstand the corrosion of acids, alkalis and other organic solvents, and can withstand temperature changes in the production process. Its main role is to increase the distribution point of gas or liquid, support and protect the active catalyst with low strength.
