Metal Raschig Ring
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 ring can be a variety of materials, such as carbon steel, stainless steel 304,304 L, 410,316,316 L, etc. to choose from.
Metal Raschig ring was first developed as a random packing. Its shape is simple, and its height is equal in size to its diameter. It has excellent acid resistance, can resist various acids other than acid hydrofluoric acid (HF), and is resistant to high temperature and aging. It is made of metal sheet, and its height is equal to its diameter. The commonly used size is 25mm~75mm (some as small as 6mm and as large as 150mm). The metal ring is 0.8mm~1.6mm, and the wall of the ring should be as thin as possible when the strength permits. Although the mass transfer performance of the Raschig ring is not ideal, it is still used by some factories due to its simple structure, easy manufacture and low price.
