Metal Raschig Rings: Cost-Effective Packing for Corrosive & High-Temp Services
As the pioneering random packing since 1914, Metal Raschig Rings remain essential for harsh chemical processes where simplicity and corrosion resistance outweigh efficiency demands. Ideal for acid scrubbing, quenching towers, and support layers.
Parameter | Specification |
---|---|
Materials | 304/316 SS, Carbon Steel, Titanium, Copper |
Size Range | DN 15 (½") to DN 100 (4") |
Surface Area | 60-140 m²/m³ (size-dependent) |
Void Fraction | 70-80% |
Wall Thickness | 0.5-2.0 mm (±0.1mm) |
Operating Temp. | -200°C to +750°C (SS304) |
Pressure Drop | Higher vs. modern packings (e.g., Pall Rings) |
Certifications | ASTM B366, ISO 9001 |
1.Robust Simplicity
Smooth cylindrical geometry resists fouling in dirty gases/slurries.
Thicker walls (up to 2mm) vs. advanced packings for abrasive media.
2.Corrosion Defense
316L SS: Chloride-rich environments (e.g., seawater cooling)
Titanium: Hot HCl/Cl2 scrubbers (≤200°C)
Copper: Sulfuric acid regeneration
3.Economic Efficiency
40-60% lower cost than Pall Rings or Saddles.
Ideal for support beds under structured packing.
