What are the uses of Pall ring packing of different materials?

Pall ring packing is divided into three materials: ceramic, metal, plastic, etc. Among them, metal materials: 304, 316, 316L, carbon steel, 201, 410, etc. Among plastic materials: PP, RPP, CPVC, PVDF, PVC, PTFE, FEP, PFA, etc. Among them, plastic Pall ring packings are generally divided into three shapes: rice-shaped, #-shaped, +-shaped, and other special-shaped Pall ring packings.
Advantages of plastic Pall ring packing: light weight, not fragile, heat-resistant, chemical-resistant, etc. Disadvantages: Not resistant to high temperatures, strong acids, strong alkali, easy to oxidize.
Advantages of ceramic Pall ring packing: acid resistance, alkali resistance, heat resistance, good oxidation resistance, low price, etc. Disadvantages: Fragile, bulky, and inconvenient to install.
Advantages of metal Pall ring packing: moderate weight, not fragile, moderate heat resistance, acid and alkali resistance. Disadvantages: Not resistant to strong acid and alkali, high price.
Plastic Pall ring packing is suitable for medium and low temperature (60-150 degrees) stripping, absorption and washing towers in petroleum, chemical, chlor-alkali, gas, environmental protection and other industries, as well as carbon dioxide degassing towers, ozone contact reaction towers, etc. as contact Packing and other reaction towers.
Ceramic Pall ring packing is suitable for carbon dioxide degassing tower, acid mist purification tower, ozone contact reaction tower, etc. as its contact packing and other reaction towers.
