Metallic Packing Series
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.
MEPC 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.
1.Conjugate Ring
The conjugate ring was developed by south china institute of Technology. It is lower pressure drop greatly capacity and high officiency.

2. Rasching Ring
The advantages of metal packing are less resistance, less compression decreasing,high separating,cold and heat proof, long longevity.
Material: 1Cr18Ni9Ti stainless steel, A3 carbon steel, other materials can be selected to order by users such as 604 Ls, 316 Ls,etc.
Use and give an example :
Rectification of methyl alcohol
The hard alcohol is separated form hard ketone
