Wedge Wire Well Screen: Material & Structural Integrity
- Premium Materials:
- 304/316 Stainless Steel: Corrosion-resistant (PREN ≥24) with 0.1–5 mm slot widths, ideal for freshwater wells or brackish aquifers.
- Duplex 2205/2507: High chloride resistance (PREN ≥35) and tensile strength (≥550 MPa) for offshore oil wells or coastal groundwater extraction.
- PVC-Coated Carbon Steel: Economical option for agricultural irrigation wells with abrasion-resistant epoxy layers (AWWA A100 compliant).
- Titanium Alloys: For geothermal wells or high-salinity environments (e.g., saltwater intrusion zones).
- Advanced Engineering:
- V-Shaped Wedge Wire Profile: Laser-welded wires (1–15 mm pitch) for non-clogging, self-cleaning performance in sandy aquifers.
- Triple-Rib Reinforcement: 360° welded support rods (6–25 mm thickness) to withstand collapsing pressures up to 200 bar in deep boreholes.
Wedge Wire Well Screen: Performance Advantages
- Optimized Hydraulics:
- High Open Area (10–30%): Maximizes flow rates (up to 1,500 m³/day) while minimizing drawdown in high-yield wells.
- Precision Slot Sizes: ±0.02 mm tolerance for uniform sand retention (e.g., 0.15 mm slots for 95% sand control).
- Durability Enhancements:
- Electropolishing/Passivation: Reduces biofilm adhesion (Ra ≤0.4 µm) for potable water wells (NSF/ANSI 61 certified).
- Hot-Dip Galvanizing (HDG): 85 µm zinc coating for corrosion protection in acidic mine drainage systems (ASTM A123 compliant).
- Operational Versatility:
- Temperature Range: -50°C to 300°C (suitable for Arctic permafrost wells to steam-assisted oil recovery).
- Pressure Ratings: API 5C5 compliant for 5,000 psi applications in hydraulic fracturing zones.
Wedge Wire Well Screen: Precision Manufacturing & Quality Assurance
- Cutting-Edge Fabrication:
- Resistance Welding: Automated TIG welding ensures ≤0.1 mm weld uniformity (per ISO 5817 B级).
- Slot Calibration: Laser-guided CNC machining for ±2% slot consistency (critical for sand control packs).
- Rigorous Testing Protocols:
- Sand Retention Testing: Validates 98% particle retention efficiency (per API RP 19B).
- Hydrostatic Collapse Testing: Confirms structural integrity at 1.5x rated pressure (e.g., 300 bar for 200 bar screens).
- Material Traceability: Full EN 10204 3.1/3.2 MTRs with NACE MR0175 compliance for sour service.
- Custom Configurations:
- Slotted vs. Louvered Designs: Axial, helical, or staggered patterns for gravel-packed wells or natural development.
- Flanged, Threaded, or Welded Ends: Compatible with ANSI B16.25 or ISO 11960 for well casing integration.
Wedge Wire Well Screen: Industry-Specific Applications
- Water Resources:
- Municipal Water Supply: 316SS screens (0.2 mm slots) for high-capacity production wells (AWWA A100-19).
- Agricultural Irrigation: PVC-coated screens (2 mm slots) for silt-laden riverbank filtration.
- Oil & Gas:
- Sand Control in Horizontal Wells: Duplex 2205 screens (0.25 mm slots) with wire-wrapped gravel packs (API 19SS compliant).
- Produced Water Reinjection: 2507 duplex screens (50 µm slots) for offshore disposal wells.
- Environmental Remediation:
- Contaminant Extraction Wells: Titanium screens (1 mm slots) for acidic plume remediation (EPA 542-R-12-015).
- Groundwater Monitoring: 304SS screens (0.5 mm slots) with lockable well caps (ASTM D5092).
- Mining & Geothermal:
- Dewatering Wells: HDG carbon steel screens (5 mm slots) for open-pit mine drainage.
- Geothermal Brine Extraction: Alloy 625 screens (3 mm slots) for 300°C geothermal reservoirs.
