What is Wedge Wire Screen

What is Wedge Wire Screen?

A wedge wire screen (also known as profile wire screen, Vee-Wire screen, or Johnson screen) is a type of screen made of specially profiled wires that are resistant and welded onto support rods. The unique feature of a wedge wire screen lies in its distinctive "V" shaped profile of the surface wires. This shape allows for a larger opening on the inside of the screen compared to the surface, significantly enhancing its performance.

The key components of wedge wire screen strainers:

• Profile Wires (Surface Wires): These are the "V" shaped wires that form the filtration or separation surface. The V-shape minimizes clogging and maximizes flow.

• Support Rods: These are the parallel rods that the profile wires are welded onto, providing structural integrity and strength to the screen.

• Slot Opening: This is the space between the profile wires, determining the size of the particles or fluids that can pass through the screen. The slot opening is precisely controlled during manufacturing.

Wedge Wire Screens Manufacturing Process

The manufacturing process of a wedge wire screen is critical to its performance and durability.

• Wire Forming: Profile wires are meticulously formed into the desired "V" shape.

• Assembly: The profile wires are positioned around the support rods, ensuring precise spacing to achieve the desired slot opening.

• Resistance Welding: A specialized resistance welding process securely joins the profile wires to the support rods at each intersection. This creates a strong and durable screen structure.

• Finishing & Quality Control: The screen undergoes rigorous quality control checks to ensure dimensional accuracy, weld integrity, and overall performance before being shipped.

Key Advantages of Wedge Wire Screens

Wedge wire screens offer a range of advantages that make them a preferred choice in many applications:

• High Open Area: The unique design maximizes the open area, allowing for higher flow rates and reduced pressure drop.

• Non-Clogging Design: The V-shaped profile prevents particles from becoming trapped, minimizing clogging and reducing maintenance.

• Precise Slot Openings: Accurate slot openings ensure efficient separation and filtration of specific particle sizes.

• High Strength and Durability: The robust construction and welding process provides excellent strength and long service life.

• Versatile Applications: Wedge wire screens can be customized in various shapes, sizes, and materials to suit diverse applications.

• Easy to Clean: The smooth surface and non-clogging design simplify cleaning and maintenance.

• Customization: The screens can be designed to fit a wide variety of applications.

Common Applications of Wedge Wire Screens

Wedge wire screens are used extensively across numerous industries:

1. Water and Wastewater Treatment: Filtration of solids, removal of debris, and pre-filtration for reverse osmosis systems.

2. Food and Beverage Processing: Screening of grains, seeds, and other food products; juice filtration.

3. Mining and Mineral Processing: Separation of solids from slurries, dewatering, and classifying minerals.

4. Oil and Gas Industry: Sand control in wellbores, oil/water separation, and filtration of drilling fluids.

5. Pulp and Paper Industry: Fiber recovery, white water filtration, and chip screening.

6. Agriculture: Irrigation water filtration, manure separation, and grain cleaning.

7. Pharmaceuticals: Filtering of solids and active ingredients in pharmaceutical preparations.

8. Chemical Processing: Removing contaminants from liquid chemical solutions.

9. Architectural: Decorative screens, facades, and other design elements.
