Wedge Wire Screen



Wedge wire screen is a robust filtration device constructed from parallel V-shaped (wedge-shaped) wires welded onto support rods. The triangular cross-section of the wires creates precise, continuous slots that allow for efficient particle separation. The wide end of the wedge faces the flow direction, minimizing clogging by directing debris away from the slots.

Wedge wire screens excel in demanding filtration roles, offering precision, durability, and adaptability across industries. Proper selection based on operational parameters ensures optimal performance and cost-effectiveness.

  Customization for Specific Needs

• Wedge wire screens are engineered to adapt to unique industrial demands. Key customization parameters include:

  • Slot Size: Adjusted by spacing wedge wires (from 20 µm to 3,000 µm) to target specific particle retention.

  • Material Selection:

    • Stainless steel (304/316): Corrosion resistance for water treatment or food industries.

    • Duplex steels: High chloride resistance for desalination plants.

    • Hastelloy/Titanium: Extreme chemical/thermal resistance for mining or oil/gas.

      • Structural Reinforcements:

        • Additional support rods or frames for high-pressure environments (e.g., oil drilling).

        • Reinforced edges for abrasive applications (e.g., mining slurries).

      • Surface Treatments:

        • Electropolishing for sanitary applications (food/pharma).

        • Coatings (e.g., rubber, epoxy) to reduce wear in high-abrasion settings.
