Ceramic super intalox saddle 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.

Advantage
● 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.
● The porcelain’s specific gravity is 2.3-2.4g/cm3 and an average heat capacity (between 20℃ and 500℃ of 0.22 cal/g.℃)
● XINGFENG ceramic super intalox saddles softening point is 1400℃ min. And they show good thermal shock resistance during repeated cycling between 20℃ and 820 ℃.
