Stripping Tower 76 Mm 410s 1 Mm Thickness Stainless Steel Pall Rings
1. Stainless Steel 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.

3. Benefits of Stainless Steel Pall Rings:
High resistance to fouling
Multiple materials available
High temperature applications
Mechanically robust, lesser probability of breakage
Good liquid/gas distribution and high mass transfer efficiency
4. Stainless Steel 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.
