For high-chloride or marine applications, we recommend 316/316L stainless steel (Mo ≥2.1%) or Duplex 2205 (PREN ≥35) for superior pitting and stress corrosion cracking resistance.
Yes, our tubes are ideal for pharma. We offer electropolishing (Ra ≤0.4µm) and 316L alloys that are compatible with CIP/SIP systems to prevent biofilm adhesion.
Depending on the wall thickness (up to 12mm) and material, our tubes can withstand pressures up to 150 bar, with hydrostatic validation provided per ASME standards.
Absolutely. We offer staggered, inline, and radial layouts with open areas ranging from 5% to 60%, optimized for flow rates up to 500 m³/h.
304SS is suitable for general water treatment in mildly corrosive environments. 316L is required for chlorinated water or chemical processing due to its added Molybdenum content.
Yes, our stainless steel filter tubes maintain structural integrity across a thermal range of -200°C (LNG screens) up to 900°C (incinerator ash filters).
