Wedge Wire Wrapped Screen: Material & Construction
- High-Performance Materials:
- 316/316L Stainless Steel: Corrosion-resistant (PREN ≥27) with 0.1–5 mm slot widths, ideal for seawater desalination or acidic slurry filtration.
- Duplex 2205/2507: Combines high strength (550–800 MPa yield) and chloride resistance (PREN ≥35) for offshore oil separators or mineral processing.
- Hastelloy C-22: Resists oxidizing and reducing environments (per ASTM G28), used in chemical reactors or sulfuric acid recovery systems.
- Carbon Steel with Epoxy/PVDF Coating: Cost-effective for wastewater treatment or agricultural irrigation (NACE MR0103 compliant).
- Advanced Structural Design:
- V-Shaped Wedge Wires: Precision-welded profile wires (1–10 mm pitch) for non-blinding, self-cleaning action.
- Support Rod Reinforcement: Laser-welded rods (3–20 mm diameter) to withstand 200+ bar in oil & gas well screens.
Wedge Wire Wrapped Screen: Performance Optimization
- Superior Flow Dynamics:
- High Open Area (15–40%): Minimizes pressure drop (ΔP 0.3 bar) in high-viscosity fluids (e.g., crude oil, pulp slurry).
- Uniform Slot Geometry: ±0.05 mm tolerance for micron-level accuracy in pharmaceutical crystallization or food-grade filtration.
- Surface Enhancements:
- Electropolishing: Achieves Ra ≤0.2 µm for hygienic compliance (per EHEDG/3-A) in dairy processing or biopharma.
- Hot Isostatic Pressing (HIP): Eliminates micro-cracks for API 5CT compliance in sand control screens.
- Operational Resilience:
- Temperature Range: -200°C to 550°C (suitable for cryogenic LNG to thermal oil recovery).
- Pressure Ratings: Up to ASME B31.3 Class 2500 for subsea pipelines or geothermal wells.
Wedge Wire Wrapped Screen: Precision Manufacturing & Testing
- State-of-the-Art Fabrication:
- Resistance Welding: Automated TIG welding ensures ≤0.1 mm weld deviation (per ISO 5817).
- CNC Slot Calibration: Laser-cut slots with ±2% dimensional accuracy for sieve trays or RO membrane guards.
- Rigorous Quality Control:
- Bubble Point Testing: Validates slot integrity (per ASTM E128) for 10–500 µm particle retention.
- Hydrostatic Burst Testing: Validated at 2x working pressure (e.g., 400 bar for 200 bar systems).
- Material Certifications: Full EN 10204 3.1/3.2 traceability with NORSOK M-650 compliance.
- Custom Configurations:
- Slotted vs. Perforated Designs: Radial, axial, or helical wraps for dewatering drums or fluidized bed reactors.
- Flanged or Threaded Ends: Compatible with ANSI B16.5 or ISO 7/1 standards for pipeline integration.
Wedge Wire Wrapped Screen: Industry Applications
- Oil & Gas:
- Sand Control Screens: Duplex 2507 screens with 0.3 mm slots for horizontal well completions (API 19SS compliant).
- Produced Water Filtration: 316L screens (200 µm slots) in offshore separators (ISO 13535 certified).
- Water & Wastewater:
- Desalination Intake Screens: 2205 duplex screens with 1 mm slots for reverse osmosis pre-filtration.
- Mining Slurry Dewatering: Carbon steel screens (5 mm slots) with abrasion-resistant coatings for tailings management.
- Chemical & Petrochemical:
- Catalyst Retention: Hastelloy C-22 screens (100 µm slots) in fixed-bed reactors (ASME BPVC compliant).
- Polymer Pellet Screening: Electropolished 316SS screens (2 mm slots) for extrusion line purity control.
- Food & Beverage:
- Sugar Crystallization: 3-A compliant screens with 0.5 mm slots for crystal size classification.
- Brewery Lauter Tuns: Sanitary wedge wire floors for wort separation (per FDA CFR 21).
- Power & Energy:
- Geothermal Well Screens: Titanium-clad screens for brine filtration in 450°C geothermal fields.
- Biomass Gasification: High-temperature screens (Alloy 625) for syngas particulate removal.
