Ceramic Pall Ring Packing

Ceramic Pall Ring packing has excellent acid resistance and heat resistance. It can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature conditions. Consequently the application range is very wide. The packing can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers and actifier columns in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc. Technical data Spec.D*H*T(mm)Surface area (m²/m³)Free volume (%)Number per m³Bulk density (Kg/m³)Dry Packing Factor(m-1)Ø 2525*25*32207354000620565Ø 3838*38*41507513400570356Ø 5050*50*5120786800550252Ø 8080*80*875801950520146 Chemical composition SiO2Al2O3Fe2O3CaOK2O+Na2O>70%23-30%<1%<1-2%<2-4% Physical properties IndexValueSpecific gravity(g/cm3)2.25-2.35Water absorption(%)<0.5Acid-resisting strength, %Wt.
