SS Pall Rings Various Types 6mm - 90mm Custom Size ISO9001 Certification
Pall rings may be the most widely used metal random packings. There are many tests and experiments done with pall rings, as well as many results or graphics for reference.
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. If they are more suitable to your project than normal sizes in your opinion, we are happy to be able to help with those. Please refer to an enriched specification table below:

Pall ring was invented by German BASF in 1940s. It was an improvement of the Raschig ring. The difference for the Pall Ring is the addition of two rows of punched and formed fingers. This adjustment provides a significant performance increase: the capacity and efficiency is improved and the pressure drop is reduced. Finally, the use of pall ring indicates opening pore type packing was accepted by the world gradually.
1. Pall rings, have more than 50% higher capacity than raschig ring.
2. The pressure drop is only half of the raschig ring.
3. The relative efficiency is about 30% higher than that of raschig ring.
