High Flux & Specific Surface Area Plastic Pall Ring (PP/PE/PVC/PVDF) – Corrosion Resistant Industrial Chemical Tower Packing
Products introduction
As a high-efficiency industrial tower packing component, the Plastic Pall Ring adopts a robust ring structure with an optimized aperture ratio. Each window opening of the ring is equipped with 5 inward-inclined tongue-shaped tabs, and the upper/lower window positions are staggered—this design allows the open area to account for ~30% of the total surface, effectively guiding smooth fluid flow across the tower, fully utilizing the inner surface area, and creating unobstructed pathways for gas-liquid interaction.
Key Traits
- High specific surface area & large processing flux
- Low pressure drop during long-term operation
- Elevated flooding point for stable tower load
- Uniform contact between gas and liquid phases
- Superior acid-alkali corrosion resistance (compatible with PP/PE/PVC/PVDF/PTFE materials)
- Lightweight construction (low specific gravity)
Core Benefits
- The staggered tongue-tab structure boosts mass transfer efficiency while reducing operational energy consumption, supporting high-throughput industrial processes.
- Multi-material options (PP/PE/PVC/PVDF/PTFE) ensure excellent adaptability to harsh chemical environments, with long service life and low maintenance costs.
- Lightweight and modular sizing (16/25/38/50/76mm) simplify on-site installation, disassembly, and tower load reduction.
Application Scope
These plastic tower packing components are widely applied in petroleum processing, chemical manufacturing, wastewater treatment, coal gas purification, and scrubber tower systems, with a maximum service temperature of 280°C (adjustable based on material type).
