Professional Manufacturer of Ceramic raschig rings. Size:15mm 16mm 25mm 40mm 50mm 80mm 100mm 150mm ISO9001:2000 Introduction:Raschig ring is the earliest developed random packing,it's small tube cutting, which outside diameter is equal to its height, providing a surface for (re)evaporation of the most volatile part in the refluxing distillate. 

With the characters of high mechanical strength, high chemical stability, and excellent heat endurance, Ceramic Raschig Ring can resist high temperature, acid (except HF), alkali, salt and various organic solvents. It's widely applied in various packing towers of desiccation, absorption, cooling, washing, and regeneration in industries of petrochemical, chemical, metallurgy, gas and oxygen generation. For raschig ring with big size over 100mm, it's usually filled in the column orderly. If its size is less than 90mm, raschig ring is stacked in the column randomly.
