Our acid-resistant porous stainless steel tubes are purpose-built for distillation column systems operating in aggressive chemical environments. Designed to provide uniform vapor-liquid distribution, support mass transfer efficiency, and withstand acidic corrosion, these components are ideal for petrochemical, pharmaceutical, and specialty chemical industries.
✅ Uniform Distribution
The porous structure enables even distribution of vapor or liquid across packed or tray columns, improving contact efficiency and separation performance.
✅ Acid-Resistant Material
Manufactured from 316L stainless steel, Duplex, or Hastelloy, our tubes offer superior corrosion resistance in processes involving HCl, H₂SO₄, organic acids, or other aggressive chemicals.
✅ High Temperature & Pressure Resistance
Withstand continuous operation at up to 600°C and 20 MPa, perfect for energy-intensive distillation operations.
✅ Customizable Pore Size & Geometry
Pore sizes from 0.5 to 20 microns available, optimized for your system’s pressure drop, flow distribution, and process needs.
✅ Cleanable & Reusable
Durable sintered metal construction allows for backflushing, ultrasonic cleaning, and long service life even under corrosive cycles.
