Metallic Corrugated Tower Packing £º
Standard metallic packing includes: metallic perforated corrugated plate, metallic thornlike perforated corrugated plate, metal plate and corrugated net, metallic threadlike perforated corrugated plate, corrugated metal wire net. They are widely used in separating heat sensitive materials, such as in vacuum fraction processes in the petroleum, chemistry, flavour factory and medicine industries. They can also be used in isotope separation.
