Metal Corrugated-plate Packing/structrued packing: It is formed from vertical sheets of corrugated metal with the angle of the corrugation reversed in adjacent sheets to form a open structure with inclined flow channel. Its structure can not only change the distribution of liquid, but also increase the transfer efficiency. owing to its advantage, including big flow, low resitance,high transfer efficiency, strong unblocking ability, it is widely apply in rectifying, adsorption, extraction. it is effectively structured packing which applied in chemical industry ,fertilizer, refine, petrochemical,natural gas.
