Pall Ring

PP Plastic Pall Ring Packing

Plastic Pall Ring Packing has distinctive features, making it effective in industrial applications. It provides large void space, facilitating fluid flow and reducing clogging risk. This allows gases and liquids to move freely, enhancing system performance. Also, it has a low pressure drop, crucial for energy efficiency and cost - reduction, achieved through an optimized design for smooth fluid passage with minimal resistance.

Plastic Pall Ring Material Properties

Chemical Resistance

Resistant to most acids (except strong oxidizing acids), bases, alcohols, and solvents. Not suitable for aromatic/chlorinated hydrocarbons or high-temperature oxidizing agents.

Temperature Range

-10°C to 120°C (continuous use), depending on grade. Avoids deformation at moderate temperatures.

Lightweight & Durable

Low density (0.9–0.91 g/cm³) for easy handling; resistant to corrosion and abrasion.

Plastic Pall Ring Advantages

High Efficiency: The internal crossbars and windows create turbulence, enhancing mass transfer (higher surface area per unit volume than Raschig rings).

Low Pressure Drop: High void fraction reduces resistance to gas/liquid flow, lowering energy consumption.

Cost-Effective: PP is cheaper than materials like PTFE or PVDF, making it ideal for non-extreme conditions.

Easy Installation: Lightweight and random packing (no structured alignment needed), simplifying column filling.

Made of polypropylene (PP) material, it features excellent corrosion resistance, light weight, high strength and long-term stability. It is suitable for devices such as absorption towers, scrubbers, cooling towers and biological filters, and is particularly suitable for environmental protection and chemical processes such as waste gas treatment, acid mist purification and gas drying, which can optimize separation efficiency and save energy and reduce consumption.

Typical applications

Environmental protection engineering: Waste gas treatment (VOCs absorption, acid mist purification), wastewater treatment (biological filter, desulfurization tower).

Chemical separation: gas-liquid mass transfer processes in distillation towers, absorption towers, and extraction towers.

Energy industry: natural gas dehydration, carbon dioxide capture, etc.

Pharmaceuticals and food: Sanitary-grade processes such as solvent recovery and distillation purification.
