Flux , the resistance is small , high separation efficiency and operating flexibility

1)Metal pall ring is the new 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 .

2) It is a model of metal random packing,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.

3)Specification of metal random packing:
