SS304 Corrugated Metal Structure Packing For Distillation Towers
Description of SS304 Corrugated Metal Structure Packing
SS304 corrugated metal structured packing, also known as perforated corrugated plate packing, is assembled from multiple pieces of thin stainless steel 304 sheets stamped with dense micro holes and pressed into regular corrugated shapes. Adjacent corrugated plates are arranged in reverse inclined directions (30° or 45°), and each packing layer is stacked crosswise at 90° against the upper layer inside distillation towers to form orderly, uniform gas-liquid flow channels.
The microporous structure on plate surfaces optimizes liquid distribution and surface wettability, effectively eliminating channel flow and wall flow inside the tower. Made of high-quality SS304 stainless steel, this structured packing balances high mechanical strength, excellent corrosion resistance and stable mass transfer performance, widely adopted as core mass transfer media for atmospheric, vacuum and precision distillation towers in chemical processing.

Features of SS304 Corrugated Metal Structure Packing
- High Separation Efficiency: Large specific surface area (common models: 125Y/250Y/350Y/500Y m²/m³), sufficient gas-liquid contact area to achieve high theoretical plate numbers for precise component separation.
- Ultra-Low Pressure Drop: Regular geometric flow paths reduce gas flow resistance, saving energy consumption especially for vacuum distillation working conditions.
- High Liquid Handling Capacity: High void fraction design supports large gas-liquid flux, suitable for high-load continuous tower operation.
- Excellent Liquid Distribution: Perforated holes realize coarse & fine dual liquid distribution, strengthen horizontal fluid mixing and avoid liquid bias flow.
- Superior SS304 Material Performance: Resists oxidation, weak acid & organic solvent corrosion, stable working temperature range from -200℃ to 400℃, durable service life, easy cleaning and anti-fouling.
- Customizable Size: Can be fabricated into circular segmented packing blocks matching tower diameters from 150mm up to 12000mm, supporting OEM customized specifications.
