PVC Pall Ring Product Description

The PVC Pall Ring is a widely used random packing manufactured from polyvinyl chloride (PVC). It retains the proven Pall ring geometry—a cylindrical body with two rows of open windows and inwardly bent tongues—which ensures high voidage, uniform gas-liquid contact, and low pressure drop. PVC material provides good resistance to most inorganic acids, alkalis, and salt solutions at a lower cost than CPVC, PVDF, or PTFE. Its moderate temperature limit of 60°C makes it suitable for many cooling, scrubbing, and wastewater treatment applications where aggressive chemicals are present but process temperatures remain moderate. The smooth PVC surface also resists scale build-up, and the lightweight construction reduces tower structural load and simplifies installation.

Product Highlights

• Cost-Effective Corrosion Resistance: PVC offers good resistance to most acids, alkalis, and salt solutions at a lower material cost than CPVC, PVDF, or PTFE.
• Moderate Temperature Service: Suitable for continuous operation up to 60°C, covering cooling towers, acid gas scrubbing, and many wastewater treatment processes.
• Proven Pall Ring Geometry: Open windows and internal tongues deliver high mass transfer efficiency, large voidage, and low pressure drop.
• Lightweight & Easy Installation: Weighing far less than ceramic or metal packings, PVC Pall rings reduce tower load and simplify loading and replacement.
• Anti-Clogging & Smooth Surface: The non-porous PVC surface resists scale adhesion, while the open structure prevents blockage from moderate solids.
• Widely Available & Economical: As one of the most common plastic packings, PVC Pall rings offer reliable performance, ready availability, and low overall cost.
