Stainless Steels Metal Pall Ring Product Description Metal Tower Packing 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 thermo sensitive, decomposable, polymerizable or cokable systems, so it is widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc. Metal pall ring packing is 40 years of the 20th century in Germany, BASF, based on raschig ring developed, which used red bar made of sheet metal, out of the wall in the ring with two rows of windows within the leaf holes, each row of five windows beds into the leaf tongue ring, point to the ring center, almost in the center relative to ride up and down the location of two fenestrae staggered, the general opening of the total area of about 35% the entire loop area. Because many of the ring walls opened windows, so fill layer of gas and liquid distribution and mass transfer performance has greatly improved. Technical Parameter
