Pall ring characteristicsPall rings are annular packing materials, typically made of metal or corrosion-resistant plastic.

Structurally, they feature multiple layers of perforations in the cylinder wall and inwardly blades. Their advantages include a large specific surface area.

Uniform water distribution and enhanced fluid distribution and mass transfer efficiency making them for equipment such as scrubbing towers.

Absorption towers and deodorization towers. Step ring characteristicsStep rings feature flared tapered lip on one end based on annular-packing foundation.

Forming short stepped cylinder profile. This geometry reduces fluid resistance suppresses channeling and wall-flow.

Stabilizes gas-liquid distribution and promotes uniform packing stacking. for corn-starch washing towers demanding low pressure drop and reliable separation efficiency.

Main material selection.

Metal: High mechanical strength and thermal stability for continuous long-run service.

PP/RPP: Corrosion-resistant, lightweight and cost-effective for mild process conditions.

Stainless steel: Superior corrosion resistance for food-grade and high-spec washing circuits.
