ISO9001:2008, 1. Professional manufacturer, 2. Diameter: 25mm 38mm 50mm 76mm, 3. Material: Ceramic, Plastic,Metal - details see: https://www.machineto.com/good-quality-plasitc-ceramic-metal-pall-ring-10285229

Introduction:Pall ring has excellent acid resistance and heat resistance. It can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature conditions. Consequently the application range is very wide. It can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers and actifier columns in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc.

Plastic pall ring is made of standing up to chemical corrosion materials, such as PE, PP, RPP,PVC, CPVC and PVDF. It has feature such as high void ratio, low pressure drop, sufficient gas liquid contact, small specific weight, high mass transferring efficiency and so on.
