What materials can Pall ring packing be made of, Chemshun ceramic manufacturer tell you , there are three main materials for pall ring packing: ceramic, metal, plastic and so on. Metal material: 304.316.316L. Carbon steel. 201.410 etc. Plastic materials: PP, RPP, CPVC, PVDF, PVC, PTFE, FEP, PFA, etc. Plastic Pall ring packing is generally divided into three shapes of special-shaped Pall ring packing such as rice shape, # shape and + shape.
The advantages of plastic Pall ring packing: light weight, not fragile, heat-resistant, chemical-resistant, etc. ;Plastic PP Pall ring packing temperature tolerance range is 80℃; Plastic PVC Pall ring packing temperature tolerance range is 110℃; Plastic PTFE Pall ring packing temperature tolerance range is 220℃; PVDF Pall ring packing temperature tolerance The acceptance range is 150°C.
The advantages of ceramic Pall ring packing: acid resistance, alkali resistance, heat resistance, good oxidation resistance and low price. Disadvantages: fragile, heavy, and inconvenient to install. Ceramic Pall ring packing is suitable for carbon dioxide degassing tower, acid mist purification tower, ozone contact reaction tower, etc.
Metal Pall ring packing has the advantages of moderate weight, not fragile, heat resistance, acid and alkali resistance, etc. Defects: Not resistant to strong acids and alkalis, and expensive. The temperature tolerance range of metal Pall ring packing is -196℃~800℃. The metal will melt into liquid at about 1000℃. This is the melting point temperature. The working temperature in the use of the packed tower should be lower than this temperature.
Pall ring as chemical tower packing is used widely , Chemshun can supply you wanted pall ring in different size and materials.
