Brief Introduction of Metal Raschig Ring

Metal raschig ring is a kind of raschig ring packing.The design of the Raschig ring was invented by Friedrich Raschig and patented in 1914. It has equivalent diameter and height. This type raschig ring is mainly made from carbon steel or stainless. Other materials can be customized according to your needs. Due to its large flux and low resistance, metal raschig ring performs well in gas-liquid distribution. Compared with plastic raschig ring, metal raschig ring has higher strength and better stiffness. Although metal raschig ring has the same shape as metal pall ring, the latter's mass transfer efficiency and handling capacity are much better.
