Metal Random Packing Pall Ring Manufacturers Company
The product description
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. Hualai Pall ring is widely applied
to industry. It is still one of major annular random packing that
has been adopted. It is especially suitable for rectification
towers under vacuum to treat thermosensitive, decomposable,
polymerizable or cokable systems, so it is widely used in packing
towers in petrochemical industry, chemical fertilizer industry and
environmental protection, etc.
