In modern industrial operations, reliable solid-liquid separation is critical for maximizing efficiency and reducing maintenance costs. The wedge wire screen tube, also known as a V-wire screen, Johnson screen, or profile wire tube, has emerged as a high-precision filtration solution. Its robust structure and self-cleaning properties make it ideal for demanding applications in water treatment, oil and gas, mining, and food processing.

Wedge wire screen tubes are manufactured by welding V-shaped profile wires onto longitudinal support rods, creating a durable and precise filtration element. The main components include:
Component | Function & Features |
Surface V-Wire | The V-shaped wire, narrow side outward and wide side inward, forms the filtering slot. This design ensures precise separation and anti-clogging performance. |
Longitudinal Support Rods | Installed inside or outside the tube to maintain slot spacing and provide structural strength. |
Flow Configuration | FOTI (Flow Out-To-In): flat side outward, most common; FITO (Flow In-To-Out): flat side inward, used for reverse filtration. |
Reinforcements | Ring supports, end fittings, or flange connections enhance pressure resistance for high-pressure applications. |
The defining feature of wedge wire screens is the V-shaped slot, which provides superior non-clogging performance:
1. V-Shaped Openings: Narrow at the top and wide at the bottom, allowing particles to pass through without getting trapped.
2. Continuous Slots: Helical or straight unbroken slots provide higher open area than conventional meshes, enabling higher flow rates and lower pressure drops.
3. Precise Slot Widths: Customizable from 0.02 mm (20 microns) to several millimeters for accurate material retention.
The combination of V-shaped slots and two-point contact welding also provides self-cleaning functionality, making wedge wire screens ideal for filtering sand, sediment, and other particulate matter.
Thanks to their durability, corrosion resistance, and high mechanical strength, wedge wire screen tubes are widely used across multiple industries:
Industry | Typical Applications |
Water Treatment | Municipal and industrial water filtration, well screens, backwash filters. |
Oil & Gas | Sand control in oil wells, downhole well screens. |
Mining & Mineral Processing | Dewatering screens, hydrocyclones, centrifuge screens. |
Food & Beverage | Sugar refining, beer and beverage clarification. |
Chemical & Pulp & Paper | Ion exchange distribution tubes, water softeners, chemical reactors. |
Additionally, wedge wire screens are employed in architectural and decorative applications due to their smooth, rigid, and customizable appearance for drainage and grating solutions.
1. Non-Clogging & Self-Cleaning: V-shaped slots and two-point contact prevent particle trapping and enable easy backwashing.
2. High Mechanical Strength: Suitable for high-pressure, heavy-load, and abrasive slurry conditions.
3. High Open Area: Ensures superior filtration efficiency and high flow rates.
4. Corrosion Resistance: Commonly manufactured from stainless steel grades such as 304, 316L, Duplex, or Hastelloy, suitable for harsh environments.

Wedge wire screen tubes combine precise construction, V-shaped slots, and durable materials to deliver outstanding performance in industrial solid-liquid separation, sand control, mineral dewatering, and food processing.
Choosing the right wedge wire screen tube can improve system efficiency, reduce maintenance costs, and ensure long-term reliability. Whether standard round tubes or fully customized units with specific end fittings and flanges, wedge wire screens remain a dependable filtration solution for demanding industrial applications.
