Double layered stepped ring packing

Due to the influence of flanging, the contact between the gaps of the plastic stepped ring during packing changes from linear contact to point contact. In this way, not only do the gaps between the packing particles increase, reducing the resistance of gas passing through the packing layer, but these contact points can also serve as gathering and dispersing points for the liquid flowing along the packing surface, thereby promoting the surface renewal of the liquid film and improving the mass transfer efficiency of the packing.
