SS316 Pall Ring Metal Random Packing for Gas Scrubbing Towers 50*50*0.5mm
Description of Pall Ring
Metal Tower Packing Pall ring is a new type of random packing improved on Rasiichig ring. Compared with the later, pall ring has improved the liquid distribution of packing layer greatly, with open windows on ring sidewall. Therefore it has productivity, low resistance, operating flexible and higher efficiency. Hualai Pall ring is widely applied to industry. It is still one of major annular random packing that has been adopted. It is especially suitable for rectification towers under vacuum to treat thermosensitive, decomposable, polymerizable or cokable systems, so it is widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc.
Features of Pall Ring
- Superior Corrosion Resistance (SS316 Material)
Made from SS316 stainless steel with molybdenum content, offering excellent resistance to acids, chlorides, and harsh chemical environments. Suitable for highly corrosive gas scrubbing systems.
- High Mass Transfer Efficiency
Open structure with internal windows increases gas-liquid contact area, improving absorption, stripping, and scrubbing performance in tower operations.
- Low Pressure Drop
Optimized geometry ensures smooth gas flow through the packing bed, reducing energy consumption and maintaining stable tower operation.
- High Mechanical Strength
0.5mm thick SS316 material provides strong structural integrity, resisting deformation and long-term operational wear.
- Anti-Fouling & Anti-Clogging Design
Random packing structure reduces liquid retention zones and minimizes clogging, ensuring stable long-term operation with low maintenance.
- Large Effective Surface Area
50×50mm size offers a balanced surface-to-volume ratio, improving gas-liquid contact efficiency and separation performance.
- Excellent Temperature Resistance
Performs reliably under high-temperature conditions, suitable for chemical, petrochemical, and flue gas treatment applications.
- High Void Fraction
High porosity improves gas and liquid distribution, enhancing wetting efficiency and tower performance.
- Long Service Life
Excellent corrosion resistance and mechanical stability extend service life and reduce replacement frequency.
- Wide Industrial Application
Widely used in gas scrubbing, chemical processing, air pollution control, absorption, stripping, and distillation systems.

Applications of Pall Ring
Metal Pall Ring for Vacuum Distillation and Its Applications in Heat Transfer
Metal Pall Ring is widely used in the chemical industry for Vacuum Distillation. It is a type of industrial packing that is designed to improve the efficiency of the distillation process. Pall Rings are made of metal and have a unique shape that provides a large surface area for interaction and heat transfer, making them ideal for vacuum distillation.
The Metal Pall Ring is also used for heat transfer through multiple applications such as:
- Wet scrubbers for gas absorption
- Cooling towers for heat transfer
- Mist eliminators for liquid particle removal
- Gas absorption columns
- Gas strippers
- Air washers
