Metal flat ring packing is a kind of short open hole ring type powder packing, the material is carbon steel, stainless steel 304, 304L, 410, 316, 316L, etc.. Metal flat ring, metal flat ring in the ring with a curved rib, high - diameter ratio of 0.2 - 0.4. Flat ring packing and cascade ring has a similar structure and undo the ladder ring of the flange and the incurvate arc rib to increase the strength of filling, in heaps can orderly arrangement, reasonable flow channel structure, pressure drop, in processing capacity and mass transfer performances are improved. Due to the special ratio of height to diameter, thus ensuring that the flat metal ring and metal flat ring packing packing unified toward, an increase of bulk density, incurvate arc rib to fill layer of gas-liquid distribution is more uniform, greatly improving the separation effect, mass transfer rate high and low bed resistance, self-care ability, back mixing entrainment is small, is not easy to scale advantages.
