Metal pall ring is the new type packing which is to be improved on the basis of the rasching ring. The main difference with Raschig rings packing is open a rectangular fenestrae on the side wall, fenestrae of window leaf curved into the ring center , making the air ring wall openings , liquid distribution performance than Raschig rings the improvement , especially in the ring internal surface area can be fully utilized. It has an excellent acid & heat resistance, preventing all kinds of corrosion except for HT and be widely used in the column of drying, cooling, washing and recovery etc in Chemical, petrochemical and metallurgical industries.

Materials: stainless steels, carbon steels, aluminum, copper, bronze and aluminum permeated steels, etc.
