10. Professional FAQ: Stainless Steel Filter Element Engineering
Q1. What stainless steel grades are recommended for filter baskets exposed to seawater?
A1. SS316 and duplex stainless steels (2205, 2507) provide robust corrosion resistance in saline/brine applications. For high-chloride concentrations, super-duplex grades or titanium may be assessed.
Q2. What is “absolute” vs. “nominal” micron rating in stainless steel filter element specification?
A2. Absolute means 99.9% particle removal at stated micron size (e.g., 20μm abs), while nominal means around 85% removal efficiency. For critical processes, always specify absolute ratings.
Q3. What installation standards are typically followed?
A3. ANSI B16.5 for flange connections, ASME Boiler & Pressure Vessel code for pressure boundaries, and ISO 16889 for filter test methodologies apply. Always match customer process specs for fit-up.
Q4. How is mesh integrity assured after repeated cleaning/backwashing?
A4. Proper stainless steel filter baskets are stamped or welded to retain mesh, then pass pressure, deformation, and burst tests per EN12266. High-end products use reinforced designs to double service life.
Q5. What are typical tolerances for basket/filter sizing?
A5. Length and diameter tolerances of ±0.5mm are standard, with mesh % open area controlled to ±3%. For high-precision projects, tighter (±0.2mm) may be specified.
Q6. What surface finishes are supplied for pharma and food applications?
A6. Electropolished, mirror or RA < 0.4μm finishes prevent bacterial adhesion and ensure full compliance with FDA/EC1935/3-A Sanitary standards.
Q7. How can I confirm compatibility with aggressive process media?
A7. Request a compatibility chart or corrosion test data for your exact process fluid. For specialty acids or bases, lab immersion or ASTM G31 tests may be performed prior to full-scale deployment.
