In industrial filtration, efficiency and durability are paramount. Discover how our Wedge Wire Filter Panel excels in demanding environments.

What is a Wedge Wire Filter Panel?

A Wedge Wire Filter Panel, also known as a profile wire screen or V-wire screen, is a filter plate structure made by welding V-shaped (wedge-shaped) metal wires and support rods (usually trapezoidal or rectangular). This robust construction is commonly used in solid-liquid separation, screening, dehydration, and filtration systems across various industries. Its unique wedge-shaped structure gives it continuous gaps, a non-clogging design, high strength, and excellent corrosion resistance.

These panels are widely applied in sectors such as water treatment, papermaking, food & beverage, mining, chemical processing, and petroleum. Their precision engineering ensures efficient separation and long service life, making them a preferred choice for critical industrial applications. When you're looking for a reliable wedge wire screen for sale, our panels represent the pinnacle of quality and performance.

 

Precision-engineered Wedge Wire Filter Panel for optimal separation.

Key Features & Advantages of Our Wedge Wire Filter Panels

· Non-Clogging Design: The V-shaped wire profile creates a "point contact" with particles, minimizing clogging and maximizing flow rates. This makes them an excellent self cleaning wedge wire screen solution.

· High Open Area: Offers a larger open area compared to traditional screens, leading to increased throughput and reduced pressure drop.

· Superior Strength & Durability: Fusion-welded construction from high-quality materials, often stainless steel wedge wire screen, ensures exceptional mechanical strength and resistance to deformation.

· Corrosion & Abrasion Resistance: Typically manufactured from various grades of stainless steel (e.g., 304, 316L), providing excellent resistance to corrosive chemicals and abrasive slurries.

· Precise Slot Sizes: Consistent and accurate slot openings for fine, efficient separation and filtration, crucial for applications requiring exact particle retention.

· Low Maintenance: The self-cleaning nature and robust construction significantly reduce maintenance requirements and downtime.

· Versatile Applications: Suitable for a wide range of uses, from dewatering to sizing, often replacing traditional mesh or perforated plates with superior performance.

Manufacturing Process: Quality from the Ground Up

Our Wedge Wire Filter Panel manufacturing process follows stringent quality control to ensure superior product performance and longevity.

1. Material Selection: We primarily use high-grade stainless steel wedge wire screen materials (SS304, SS316, SS316L) sourced from certified suppliers, meeting ASTM standards for chemical composition and mechanical properties. This ensures corrosion resistance and mechanical strength.

2. Wire Shaping & Preparation: Precision machinery forms the V-shaped profile wires and trapezoidal/rectangular support rods. The wires are checked for uniformity and surface finish.

3. Automated Welding: Using advanced resistance welding or plasma welding techniques, the V-shaped wires are continuously welded to the support rods at precise intervals. This creates a strong, unitary panel with consistent slot openings. Our methods conform to AWS D1.6 (Structural Welding Code – Stainless Steel).

4. Cutting & Shaping: Panels are cut to specified dimensions, and further shaping (e.g., bending, rolling) is performed as per custom designs for applications like sieve bend screen or cylindrical filters.

5. Surface Treatment: Post-welding, panels undergo pickling and passivation to remove welding discoloration, enhance corrosion resistance, and achieve a clean, smooth surface. Electro-polishing is available for specialized applications requiring ultra-clean surfaces.

6. Quality Inspection & Testing: Each profile wire screen undergoes rigorous inspection. This includes visual checks for defects, dimensional accuracy (length, width, flatness), and precise slot opening measurement using digital calipers and optical comparators. Burst pressure tests and flow rate performance tests are conducted on samples to validate structural integrity and filtration efficiency, adhering to ISO 9001 quality management standards.

7. Packaging: Finished panels are carefully packaged to prevent damage during transit, often using wooden crates or pallets with protective wrapping.

Service Life: With proper maintenance and material selection, our Wedge Wire Filter Panel products can achieve a service life of 5-15 years or more, significantly outperforming conventional screen types.

Applicable Industries: Water Treatment, Pulp & Paper, Mining & Aggregates, Food & Beverage, Petrochemical, Chemical Processing, Waste Management, Brewing, Starch Production, and many more.

Applications & Usage Scenarios

The versatility of the Wedge Wire Filter Panel makes it indispensable across numerous industries for a variety of tasks:

§ Water Treatment: Used in intake screens, dewatering systems, clarifiers, and as underdrain media retention for ion exchange and sand filters. Ideal for applications requiring robust static wedge wire screens.

§ Pulp & Paper: For fiber recovery, dewatering, and screening processes, improving efficiency and reducing downtime.

§ Mining & Aggregates: In sizing, dewatering, and washing operations for minerals, coal, sand, and gravel. Sieve bend screen designs are particularly effective here.

§ Food & Beverage: For juice extraction, sugar refining, brewing, and starch separation, where hygiene and precise filtration are critical. Our stainless steel wedge wire screen ensures food-grade compliance.

§ Petrochemical & Chemical: As support grids in reactors, catalyst retention, and liquid-solid separation in corrosive environments.

§ Waste Management: For municipal and industrial wastewater screening and sludge dewatering.

§ Architectural & Decorative: Due to their clean lines and strength, they are sometimes used for architectural facades, sunscreens, and decorative elements.

Whether it's a fixed panel in a dewatering trough or a component in a vibratory screen, the V wire screen construction consistently delivers superior performance.
