Metal Pall rings

Metal Pall rings are industrial fillers with specific structures and widespread applications. Here is a detailed introduction to the metal Pall ring:

 

1. Definition and development background

Metal Pall ring is a filler structure developed by German BASF in the 1940s. It is a new type of filler made of metal thin plate punching based on the Lassi ring filler.

 

2. Structural characteristics

The metal Pall ring opens two rows of window holes with inner protruding tongue leaves on the ring wall. Each row of windows has five tongue leaves bent into the ring and pointing to the center of the ring. The design of these window holes has significantly improved the gas and liquid distribution and mass transfer properties in the filler layer. The positions of the upper and lower window holes are staggered with each other, and the total area of ​​the opening is generally about 35% of the entire ring area.

 

3. Product specifications

Metal Pall rings are available in a variety of specifications to meet the needs of different application scenarios. Common specifications include Φ16, Φ25, Φ38, Φ50 and Φ76, etc. These specifications correspond to different diameters, heights and wall thicknesses. For example, the metal Pall ring of Φ16 has a diameter of 16 mm, a height of 16 mm, and a wall thickness of 0.5 mm.
