| Metal tower packing is made of materials like carbon steel, stainless steel or Aluminum alloy, etc. The product has features such as thin wall, heat resistant, high free volume, high capacity, low resistance, high separation efficiency and so on. It is especially suitable for rectification towers under vacuum to treat thermosensitive, decomposable, polymerizable or cokable systems, so it is widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc. The materials of Metallic packings are mainly carbonsteel,aluminum alloy and stainless steel. Owing to its thin wall,low resistance, big void fraction and capacity,metallic packings have a high separation efficiency and are applied to handle the thermal sensitive,hard to separation and easily carbonized materials in the vacuum rectifying tower. TRANSING metal random packing includes Metal Raschig Ring, Metal Pall Ring, Metal Cascade – Mini Ring, Metal Saddle, Metal Nutter Ring, and Metal Inner Are Ring etc. Technical data of Metallic Random (Tower) Packings Name | size | specific surface area α
