Metal Pall Ring is the improvement of the Raschig Ring, open two rows of rectangular hole in the side wall of the Raschig Ring, one side of the open loop wall is still connected to the wall surface, the other side to the ring bend, the formation of the extension of the ligular, all of the ligular blade side is informed within the stretch of the lingula, the lingual side of the match in the center of the ring. Pall Ring has greatly improved the utilization rate of the inner space and the inner surface of the ring, the air resistance is small, and the liquid distribution is uniform. Compared with the Raschig Ring, the gas flux of Pall ring can be increased by more than 50%, the mass transfer efficiency of about 30%. Pall ring is a kind of widely used material.
Materials: carbon steel, 1Cr18Ni9Ti, stainless 304, 304L, 410, 316, 316L，904L, alloy steel materials and so on.
Widely used in adsorption, steaming and distilling performance, oil refinery, petrochemical industry, chemical industry and air pollution control etc., and also contracts anticorrosion engineering and environmental protection.
