Jiangxi Pingxiang Dier Chemical Filler Co., Ltd. is currently producing 25x0.5mm stainless steel Raschig rings, made of metal grade S30408. These are for a large desulfurization plant project in Shanxi, with a total quantity of 540 cubic meters. The stainless steel metal Raschig rings were developed by Germany's BASF company in the 1940s based on the Raschig ring filler. They are manufactured by stamping metal thin plates, with two rows of windows featuring inwardly projecting tongue leaves on the ring wall. Each row has five tongue leaves bending into the ring, pointing towards the center. The two layers of windows are staggered in position, and the total open area is generally about 35% of the ring's total area.

25x0.5 Stainless Steel Pall Rings, Metal S30408 Material Pall Ring Filler. The gas and liquid distribution in the filler layer and the mass transfer performance are significantly improved compared to Raschig rings due to the many window holes opened on the wall of the rings. The Stainless Steel Metal Pall Rings represent a major improvement over Raschig rings, featuring two rows of window holes with inward extending tongues on the wall. This structure enhances gas-liquid separation and maximizes the use of the inner surface of the ring. Compared to Raschig rings, the processing capacity can be increased by over 50% while pressure drop is reduced by half.
