Product Introduction of Metal Pall Ring
Pall ring is a new type of random packing improved on Rasiichig ring. Compared with the later, pall ring has improved the liquid distribution of packing layer greatly, with open windows on ring sidewall. Therefore it has productivity, low resistance, operating flexible and higher efficiency.
