When choosing a pallet ring, it's important to choose the right material for your needs. Pall rings come in various materials, including stainless steel, carbon steel, and aluminum. Some are available in special alloys, such as Monel 400 or Inconel. Regardless of what metal you use for your pallet, you'll want to choose a pallet ring that will endure.
One of the benefits of metal pall rings is that they are more corrosion resistant than plastic pall rings. Because they're made of metal, they're better suited for corrosive environments, but they are more expensive than their plastic counterparts. However, aluminum pall rings are generally cheaper and offer better corrosion resistance. A metal pall ring comes in sizes from 1'' to three''.
Another advantage of metal pall rings is that they are available in a variety of thicknesses, so they can fit a wide range of vessels. Moreover, they have high efficiency and good separation capacity. And, they are highly resistant to chemicals and withstand low pressures under vacuum.

A metal pall ring's main advantage is that it offers high loading capacity, low pressure drop, and good liquid/gas distribution. Its two rows of window holes are staggered, so that the entire ring has about 35% of its surface area. The window-holes also improve the distribution of gas, liquid, and mass between the columns of the pipe. They are also very durable, so they're perfect for deep-bed applications.randompackingfactory.com
