Metal Random Packing SS316L Pall Ring For Distillation Column

Metal Pall Ring Tower Packing is one of the most common and well-known bulk packing materials. It is made of sheet metal and has a special structure. There are two rows of windows inclined inward on the annular wall. Each row of windows has five lobes that bend inward and point to the center where the tongue contacts each other. The positions of the upper and lower windows are staggered. Generally, the area of the window is about 30% of the whole ring area. The window on the ring wall makes the distribution and mass transfer efficiency of liquid and gas in the package better than that of Raschig ring.
