Etched Filter Mesh Cylinder
Material Innovations
- High-Performance Alloys:
- Stainless Steel (316L/904L): Corrosion-resistant (PREN 35–40) with 1–200 µm pore precision, ideal for pharmaceutical sterile filtration or chemical processing in acidic environments.
- Nickel Alloys (Hastelloy C-276/Inconel 625): Withstands 1,000°C+ temperatures and aggressive media like sulfuric acid, used in petroleum refining or nuclear reactor coolant systems.
- Titanium (Grade 2/5): Biocompatible, lightweight (4.5 g/cm³), and chlorine-resistant for marine desalination or medical implantable filters.
- Polymer Composites (PTFE/PEEK): Chemically inert with 0.1–50 µm pore sizes, perfect for ultra-pure semiconductor fabrication or food-grade beverage filtration.
- Custom Geometry: Cylinder diameters from 10mm to 1,200mm, with wall thicknesses of 0.5mm–10mm and lengths up to 3,000mm.
Etched Filter Mesh Cylinder
Functional Design Features
- Precision Etching:
- Photochemical Etching: Achieves ±2µm pore uniformity for critical applications like fuel injector screens or aerospace hydraulic systems.
- Laser Etching: Creates complex patterns (hexagonal, radial) with 10–500 µm apertures for high-flow biofuel filtration or 3D-printed catalyst supports.
- Multi-Layer Construction:
- Graded Porosity: Stacked layers (5–20 µm → 50–200 µm) for progressive particle capture in oil & gas sand control or water treatment prefilters.
- Surface Enhancements:
- Electropolishing: Reduces surface roughness to Ra ≤0.2µm for biofilm resistance in biopharmaceutical bioreactors.
Etched Filter Mesh Cylinder: Fabrication & Testing
- Advanced Manufacturing:
- Photolithography: Mask-aligned etching for ±1% pore density accuracy, critical in microfluidic devices or sensor protection meshes.
- Additive Hybrid Techniques: Combines etched mesh with 3D-printed frames for custom HVAC filters or lab-on-a-chip modules.
- Quality Assurance:
- Bubble Point Testing: Validates pore size integrity per ASTM F316 (e.g., 10 psi bubble point for 5µm pores).
- Cyclic Fatigue Testing: Simulates 50,000+ pressure cycles (per ISO 2941) for industrial pump intake screens.
- Material Certifications: Full traceability with EN 10204 3.1/3.2 mill reports and RoHS/REACH compliance.
Etched Filter Mesh Cylinder: Industry-Specific Applications
- Oil & Gas:
- Downhole Sand Screens: 316L mesh with 100–300 µm slots for shale gas extraction, rated to 15,000 psi and 150°C.
- Fuel Gas Scrubbing: Multi-layer Inconel cylinders for sulfur compound removal in LNG processing.
- Biopharma:
- Virus Filtration: Single-use PES/PVDF cylinders with 20 nm pores, validated for FDA 21 CFR Part 11 compliance.
- Fermentation Air Spargers: Titanium mesh for sterile aeration in cell culture bioreactors.
