Ceramic Super Saddle Ring Packing improves on the new packing from the saddle moment, filling the smooth saddle moment to the raised fringe of the zigzag or curved sides. This layer is in the packed bed, which increases the contact gap between the packings, so that there is more gas-liquid flow and dispersion in the packing layer. It has the characteristics of pressure reduction and high mass transfer efficiency, and is widely used in the production of sulfuric acid. Drying towers and absorbers. At the same time, it has excellent acid resistance and heat resistance, and can resist the corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used under high or low temperature conditions. Therefore,the application range is very wide.

1.These super saddles are made from chemical porcelain and have excellent resistance to acids except in the case of hydrofluoric
acid.Moisture absorption must less than half a percent.
2.The porcelain’s specific gravity is 2.3-2.4g/cm3 and an average heat capacity (between 20ºC and 500ºC of 0.22 cal/g.ºC)
3.Ceramic super intalox saddles softening point is 1400ºC min. And they show good thermal shock resistance during repeated cycling
between 20ºC and 820 ºC.
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.
