Graphite Rasi ring is a graphite material of the same circle and diameter of high temperature resistance, resistance to hydrofluoric acid and strong acid, strong alkali chemical filler. The use temperature is as high as 200℃, can resist the concentration of hydrofluoric acid below 48%, to nitric acid, sulfuric acid, potassium hydroxide, sodium hydroxide strong acid and basic substances and most of the organic salts, solvents have good corrosion resistance. Its performance index (strength and hardness) by testing is better than similar specifications of imported products. Its performance index (strength and hardness) by testing is better than similar specifications of imported products.

Low graphite raschig ring packing main gas absorption, acidic gas desorption, washing and chemical fertilizer production, the actual application occasions, also as a filler in propane stripping tower and acid gas used in the absorber, such as ammonium, reforming furnace, the tower of petrochemical equipment, purification of the corrosive materials, absorption, condensation, distillation, evaporation, filtration, washing device used in industries such as strong corrosion.

● It has the characteristics of high temperature and high pressure resistance, low water absorption, stable chemical performance. Can withstand the corrosion of acid, alkali and other organic solvents, and can withstand temperature changes during production. Its main role is to increase the gas or liquid distribution point, support and protect the strength of the active catalyst is not high.
