1. Metal Pall Ring Basic Introduction:
When we talk about metal pall rings, we know it is an active market
with many users and suppliers. The users are trying to use it in
more and more applications effectively. And the factories are
improving the production methods and efficiency. Sometimes an
innovation comes out of the mutual communication, which has
enriched the scope of metal pall rings we usually talk about. For
example, except the normal sizes of metal pall rings, we do know
there are some new sizes being produced.

4. Metal Pall Ring History:
The metal pall ring random packing was developed by BASF company in
1940s on the basis of raschig ring. It is made of sheet metal by
punching and rolling. Two rows of window holes with tongue leaves
extending inside are opened on the ring wall. Each row of window
has five tongue leaves bending into the ring, pointing to the ring
center, almost connecting at the center, and the upper and lower
layers of window holes are staggered with each other. Generally,
the total area of the opening is about 35% of the whole ring area.
As a result of opening windows on the ring wall, the distribution
of gas and liquid in the packing bed and the mass transfer
performance are greatly improved compared with that in the raschig
ring. People have made plenty of study of its performance, so pall
ring is still one of the main random packing used at present.
5. Metal Pall Ring Features:
