Plastic ladder ring

The side end of the plastic stepped ring packing has been added with a flange, which not only increases the mechanical strength of the packing ring, but also increases the directional probability of the packing during placement due to the destruction of the symmetry of the packing structure. Due to the influence of flanging, the contact between the packing rings 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.

Plastic filler materials include polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), etc.

Ladder ring packing is widely used in packing towers in industries such as petroleum, chemical, chlor alkali, gas, and environmental protection.
