Raschig rings made from Carbon or Graphite are used in specific applications demanding good corrosion and thermal shock resistance. They are resistant to most acids, alkalis and solvents at temperatures as high as 150 dec. C and also display good erosion and thermal shock resistance. At the same time they have high crushing strength, thus have a long life
They are available in variable sizes such as (mm): 10,19,25,38,50 & 75 |

Ceramic random packing series |
| |
 Ceramic random packing (ceramic ring) have various types, such as: rasching ring, pall ring, cascade ring, WHJATP, special shaped saddle ring, cross-partition ring, conjugate ring, spiral ring, scrubbing ring etc.
It is broadly used in the scrubbing towers, drying columns and absorbing columns in metallurgy industry, chemical industry, chemical fertilizer industry, vitriol acid industry, coal gas industry, refine chemical industry.
