Product advantages

Excellent Acid & Alkali Corrosion Resistance

Chemically inert ceramic material resists most acids, alkalis and organic solvents (except hydrofluoric acid), stable for long-term harsh corrosive working conditions.

High Temperature Resistance & Thermal Stability

Sintered at high temperature, withstand working temperature up to 1000℃+, no deformation or cracking under frequent temperature fluctuation.

Higher Mass Transfer Efficiency & Low Pressure Drop

Unique windowed structure improves gas-liquid distribution, avoids channeling and wall flow; larger flux, lower resistance and better separation effect than Raschig ring.

High Mechanical Strength & Long Service Life

Dense ceramic structure with strong compression & wear resistance, not easy to break or pulverize under fluid scouring, greatly reduce replacement & maintenance cost.

Wide Application & Flexible Custom Sizes

Suitable for desulfurization, absorption, distillation, waste gas treatment towers; various standard sizes available, customized dimensions meet different tower design demands.

Plastic Pall Ring Product features

Ceramic pall ring is a widely used type of random tower packing, upgraded on the basis of ceramic raschig ring. With punched and folded side window structure, it greatly expands specific surface area and optimizes gas-liquid flow distribution inside the tower. Made from high-alumina raw materials after high-temperature firing, this packing boasts outstanding acid and alkali corrosion resistance, high temperature resistance and excellent mechanical strength. It features low pressure drop, large processing capacity and high mass transfer efficiency, extensively applied in absorption, distillation, stripping, desulfurization and industrial waste gas purification columns in chemical, petrochemical, fertilizer and environmental protection industries. Various conventional specifications are in stock, and customized sizes can be produced according to customers’ tower design requirements.
