Pall Ring Dimensions

The common dimensions of pall rings mainly include outer diameter, height and wall thickness. The common outer diameter range is 25mm to 100mm, the height is usually 0.4 to 0.6 times the outer diameter, and the wall thickness is determined according to the specific use of pressure and material strength, generally between 1.0mm and 3.0mm. These sizes are selected based on industry standards, practical application requirements, and the physical properties of the material.

Pall ring, as an important chemical filler, the selection of its size is directly related to the performance and use effect of the filler. Below, we will describe in detail the common sizes of pall rings and their related characteristics.

1. Outer diameter size

The outer diameter of the pall ring is its most basic size parameter, and the common outer diameter size range is between 25mm and 100mm. The selection of this range is mainly based on the diameter of the packing tower and the thickness of the packing layer required. Smaller outer diameters are suitable for smaller packed towers, while larger outer diameters are suitable for large packed towers. The size of the outside diameter directly affects the specific surface area and void ratio of the packing, and then affects the mass and heat transfer efficiency.

2. Height and size

The height of a pall ring is usually 0.4 to 0.6 times its outer diameter. This design helps to form a suitable void structure in the packing layer, which not only ensures sufficient contact between the gas-liquid two phases, but also avoids excessive pressure drop. The proper ratio of height to outside diameter is the key to ensure the optimal performance of the packing.

3. Wall thickness size

The wall thickness of the Pall ring is generally determined according to the specific use of pressure and material strength, and the common wall thickness range is between 1.0mm and 3.0mm. The thinner wall thickness can reduce the weight of the filler and reduce the cost, but at the same time, it needs to take into account its bearing capacity and corrosion resistance. The thicker wall thickness is suitable for high-pressure or highly corrosive working environments.

In summary, the common dimensions of Pall ring include outer diameter, height and wall thickness, and the selection of these dimensions needs to consider the structure of the packing tower, working conditions and the performance requirements of the packing. Reasonable size combination can ensure the best effect of Pall ring in chemical, petroleum, pharmaceutical and other fields of application.
