Пластиковое кольцо Пентагона: PP/PE/CPVC от надежных поставщиков и фабрики в Китае
📦 Product Description
🔷
Pentagon Plastic Packing is a high-efficiency random packing widely used in gas-liquid separation processes.
Based on the structural analysis of this product, the hollowed-out design accelerates liquid flow velocity to improve gas-liquid separation efficiency. The large-area wall opening prevents blockage over large surface areas. Five horizontal bar sections bent at their centers form a greater surface area for gas-liquid contact. Notably, five lower support rods are evenly distributed at the bottom — this distribution promotes liquid droplet coalescence into larger droplets. This product is recognized as a high-efficiency random packing used in separation applications.

❓ Frequently Asked Questions (FAQ)
Q What is Pentagon Plastic Packing and how does it work?
Pentagon Plastic Packing is a high-efficiency random packing designed with a hollowed-out structure that accelerates liquid flow velocity. Its five horizontal bar sections bent at the center create a larger gas-liquid contact surface, improving separation efficiency in tower columns.
Q What materials are available for Pentagon Plastic Packing?
It can be manufactured from PE, PP, RPP, PVC, CPVC, PVDF, and PTFE — all of which offer excellent heat resistance and chemical corrosion resistance for demanding industrial applications.
Q What sizes are available for Pentagon Plastic Packing?
Pentagon Plastic Packing is available in three standard sizes: 1-1/2" (38×12×1.2 mm), 2" (50×17×1.5 mm), and 3" (76×26×2.5 mm), each with different surface areas and void fractions to suit various tower designs.
Q What is the maximum operating temperature for this packing?
The operating temperature for Pentagon Plastic Packing ranges from 60°C to 280°C, depending on the material selected. PVDF and PTFE grades are suitable for higher-temperature applications up to 280°C.
Q What industries commonly use Pentagon Plastic Packing?
It is widely used in petroleum refining, chemical processing, alcohol production, chloride treatment, gas absorption, and environmental protection industries due to its excellent mass transfer efficiency and corrosion resistance.
Q What are the main advantages of Pentagon Plastic Packing over conventional packing?
Compared to conventional packing, Pentagon Plastic Packing offers a higher void fraction (up to 97%), lower pressure drop, greater flood resistance, more uniform gas-liquid distribution, lower specific gravity, and lower operational costs — making it a highly cost-effective choice for industrial separation towers.
