In the field of tower internals, raschig rings and cascade rings are two widely used packing types, both playing crucial roles in chemical and petrochemical separation processes. Though sharing the basic function of enhancing mass transfer, their structural designs differ significantly, which directly affects their performance in practical applications. Raschig rings, developed in 1914, feature a simple cylindrical structure with equal height and diameter, typically made of materials like ceramic, metal, or plastic. This classic design ensures good fluid distribution but has limitations in mass transfer efficiency, especially for high-viscosity or complex mixtures. Cascade rings, as an improved version, emerged in the 1960s with innovations such as internal flanges or folded edges. These structural enhancements reduce pressure drop while increasing the specific surface area, making them more suitable for scenarios requiring high separation efficiency, such as in refined distillation or absorption columns. As a professional packing manufacturer, Helvo stands out in the industry by offering both Raschig rings and Cascade rings with strict quality control and advanced production technology.
