1. Product Description
Ceramic Pall Ring is a open-hole ring packing,which high and diameter is the same and with 5 ligules toward inside at every floor. Usually the open surface is 30% of the whole wall surface, this character helps the liguid & gas pass in packing tower pass freely from the windows of the rings.
Ceramic pall Ring 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.
