Low Pressure Drop Plastic Raschig Ring (PP/PE/PVC) 38/50/76mm – Corrosion Resistant Industrial Chemical Absorption & Distillation Tower Packing
Plastic Raschig Ring Product Description
Plastic Raschig Ring – a classic random tower packing with roots dating back to 1914 (invented by F. Raschig) – stands as one of the earliest-developed ring-type random packings, widely trusted across industrial processing.
Featuring a simple, time-tested design (identical diameter and height), it delivers a large surface area within tower volumes, enabling efficient mass transfer between liquids and gases/vapors while maintaining a low pressure drop. Available in materials including RPP, PVC, PE, and PP, with common sizes (25mm, 38mm) tailored to diverse tower configurations.
Its bridge-type variant excels at supporting catalyst beds, while standard plastic Raschig Rings are widely applied to equipment like drying towers, absorption towers, washing towers, and regeneration towers – spanning industries such as chemical processing, metallurgy, and gas production.
