Product Description

Product Description

Plastic Conjugate Ring Packing Overview
A lightweight, corrosion-resistant bulk packing material combining annular and saddle-shaped designs, featuring:
Conjugated curve ribs: Optimizes fluid dynamics via point contact between packing units and tower walls, preventing overlap and ensuring uniform pore distribution.
Rolled edge design: Enhances structural stability and directional arrangement during random piling.
1. Material & Structural Features
Primary Materials:Polypropylene (PP)/Polyethylene (PE): Lightweight, chemically resistant (pH 2–12), suitable for low-to-medium temperature processes.
Structure:Point-contact arrangement minimizes fluid resistance and maximizes mass transfer efficiency.
Optimized aspect ratio balances void fraction and surface area.
2. Key Advantages
Low pressure drop: <120 Pa/m, ideal for vacuum distillation of heat-sensitive materials.
High mass transfer efficiency: 25% performance boost in petrochemical dehydration (e.g., TRT units).
Chemical resistance: PE/PP resists acids/alkalis; 316L stainless steel variants extend lifespan to 3+ years in pharmaceuticals.
