Welded Wedge Wire Screen

Welded wedge wire screen is a precision filtration and separation element made from V-shaped profile wire welded onto support rods. The welded construction creates a strong, stable screen surface with consistent slot openings, making it suitable for demanding industrial processes that require reliable filtration, dewatering, and solid-liquid separation.

We supply welded wedge wire screen in a variety of formats, including flat panels, curved screens, cylindrical screens, and slotted tube filters. It can be manufactured in stainless steel grades such as 304 and 316L, depending on the working environment, corrosion resistance requirement, and service life target.Request a Quote

Key Advantages of Welded Wedge Wire Construction

• All-welded structure. Each wire-to-rod intersection is resistance-welded for strong joints and consistent slot geometry over the screen’s service life, with no loose wires or moving parts.

• Continuous V-wire slots. The V-shaped profile narrows at the screening surface and widens inward, providing a self-cleaning effect that reduces clogging and blinding while maintaining high flow capacity.

• High open area & low pressure drop. Optimized wire and support rod patterns maximize open area (typically 15–65%), allowing higher throughput per unit area and lower energy consumption.

• Customizable geometry. Slot size, wire profile, support rod spacing, diameter/length, and end connections can be tailored to process conditions, pressure ratings, and installation constraints.

• Broad material portfolio. Standard stainless steel grades (304/304L, 316/316L) and special alloys (321, Duplex/Super Duplex, Alloy 20, Cu-Ni, Hastelloy C-276, Monel) are available for corrosive, high-temperature, or abrasive services.

Material Options & Selection Guidance

Material choice depends on fluid chemistry, temperature, chloride content, and mechanical load. Common options include:

• SS 304/304L. Cost-effective for mild environments and low-chloride water; widely used in general industrial and food applications.

• SS 316/316L. Better resistance to pitting and crevice corrosion in seawater, brackish water, and many chemical environments; common in marine, coastal, and wastewater applications.

• Duplex / Super Duplex. High strength and excellent corrosion resistance for heavy-duty, high-pressure, and highly abrasive slurries.

• Special alloys. Alloy 20, Cu-Ni, Hastelloy C-276, Monel 400, titanium, and others for extreme corrosion or high-temperature service.

For each project, we review process data and, if available, media/water analysis to recommend the most cost-effective grade that meets service life requirements.

Applications Across Industries

Welded wedge wire screens are used wherever precise, non-clogging solid–liquid separation is required:

• Water & wastewater treatment: intake screens, bar screens, headworks screening, membrane protection, underdrains, and sludge dewatering screens.

• Mining & mineral processing: classification, sizing, dewatering, coal washing, tailings management, and trommel/rotary drum screens.

• Food & beverage: sugar centrifugation and drying, starch recovery, brewing lauter tuns and mash filters, juice and syrup filtration, and fish/food intake screens.

• Petrochemical & chemical processing: catalyst support screens, resin traps, reactor internals, and corrosive service filtration.

• Pulp & paper: savealls, screen baskets, and headbox screens for fiber recovery and pulp washing.

• Power & desalination: cooling water intake screens and fine filtration for thermal and membrane desalination plants.
