Metal Raschig Ring will have a variety of materials, such as carbon steel, Aluminum alloy,stainless steel 304,304 L, 410,316,316 L, Red Copper ,etc. to choose from.
Metal raschig ring in 1914 by F. Raschig developed. It was one of the first was invented by a fixed geometry of the bulk packing. Its simple shape, height and diameter of the same size. metal raschig ring is widely used in many areas.
Metal raschig rings is made of material 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 petrochemical engineering, fertilizer, enviromental protection fields as one of the tower packings. Such as vapor washing tower, purification tower,etc.
