Ceramic random tower packing:1) Excellent acid and heat resistance (acid: 99.8%; alkali: 92%), except against corrosion by hydrofluoric acid 2) Due to its superior chemical and physical specialties, ceramic packing is widely used for drying columns, adsorbing columns, cooling towers and scrubbing towers in the chemical, metallurgical, coal gas and oxygen production industries3) Main types: saddle ring, supper saddles, raschig ring, cross partition ring, pall ring, conjugate ring, cascade ring Plastic random tower packing:1) Made of PE, PP, PVC, PVDF, CPVC 2) Plastic packing has the advantages of high void ratio, low pressure drop, low mass transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high efficiency of mass transfer3) These various plastic tower packing are widely used in petroleum and chemical industries, alkali chloride industries, gas industries and environmental protection industries with max. temperature of 150°C4) Main types: pall ring, polyhedral hollow ball, conjugate ring, teller rosettering, cascade ring, saddle ring, helix ring, hollow ball.Metal random tower packing:1) Made of carbon steel, stainless steel and aluminum alloy2) Because of its thin wall, heat resistance, large void, high capacity, low resistance and high separation efficiency, metal tower packing is widely utilized in vacuum rectifying towers; especially for temperature sensitive, and decomposable3) Main types: pall ring, hypack, raschig ring, saddle ring, cascade ring producing area:China payment:T/T, irrevocable L/C at sight
