Engineered for extreme environments, our Wedge Wire Well Screens provide unmatched structural integrity and precision filtration for groundwater extraction and industrial fluid management. By utilizing a V-shaped profile and advanced laser-welding technology, these screens ensure a non-clogging, self-cleaning performance that maximizes flow rates while maintaining rigorous sand control standards.
From municipal water supply and agricultural irrigation to high-pressure oil and gas applications, our screens are manufactured from premium materials including 316L Stainless Steel, Duplex 2205/2507, and Titanium alloys. Each unit is rigorously tested for hydrostatic collapse and particle retention to ensure long-term reliability in the most challenging geological formations.

| Performance Metric | Standard Slotted Pipe | Wedge Wire Screen | Business Impact |
|---|---|---|---|
| Sand Control Efficiency | Low (High Sand Inflow) | Ultra-High (98% Retention) | Reduced Pump Wear |
| Water Flow Rate | Limited (Low Open Area) | Maximum (up to 30% Open) | Higher Yield/Well |
| Clogging Rate | High (Linear Slots) | Very Low (V-Profile) | Lower Maintenance Cost |
| Service Lifespan | Short (Corrosion Prone) | Long (Duplex/Titanium) | Lower CapEx over time |
| Installation Risk | Moderate (Collapse Risk) | Low (High Strength) | Reliable Borehole Life |
The V-shaped profile allows particles smaller than the slot width to pass through without bridging, creating a "self-cleaning" effect that prevents the screen from clogging and maintains high flow rates.
Duplex 2205 or 2507 stainless steel is recommended due to high chloride resistance (PREN ≥35) and superior tensile strength (≥550 MPa), preventing pitting and stress corrosion cracking.
We employ triple-rib reinforcement with 360° welded support rods and conduct hydrostatic collapse testing at 1.5x the rated pressure to ensure the screen can withstand extreme borehole pressures up to 200 bar.
Yes, we offer Titanium alloys and Alloy 625 screens specifically designed for geothermal brine extraction, capable of withstanding temperatures up to 300°C and highly aggressive chemical environments.
Our products comply with API 5C5 (oil/gas), AWWA A100 (water), NSF/ANSI 61 (potable water), and NACE MR0175 (sour service), ensuring global industry standard compliance.
Using laser-guided CNC machining, we achieve a slot tolerance of ±0.02 mm, allowing for precision sand retention (e.g., 0.15 mm slots for 95% sand control) tailored to the specific grain size of the aquifer.
