Wedge Wire Screen

Overview of Wedge Wire Screens

Wedge wire screens, also known as profile wire screens, are precision-engineered filtration and separation products designed for demanding industrial environments. Their unique construction ensures exceptional strength, non-clogging performance, and precise slot openings that are consistent across the entire screen surface. These screens are widely used in water intake, wastewater treatment, food processing, mining, chemical processing, and many other industries where reliable liquid/solids separation is critical.

The manufacturing process involves winding a triangular or wedge-shaped profile wire around a series of support wires. The continuous slot opening created by this design allows for efficient flow while effectively retaining solid particles of a specified size. The V-shaped opening prevents particles from becoming wedged, reducing clogging and facilitating easy cleaning.

Materials and Construction

Wedge wire screens are available in a wide range of materials to suit different operating conditions. Common materials include stainless steel grades 304, 304L, 316, 316L, and 904L, as well as duplex stainless steels, Hastelloy, Inconel, Monel, and other special alloys. The selection of material ensures excellent corrosion resistance, high strength, and longevity even in harsh chemical or high-temperature environments.

Material: Wedge wire screen is supplied in stainless steel and other special steel metals and alloy metal screens, including but not limited to 304, 316, 316L, 2205 duplex, and titanium, ensuring compatibility with a wide range of process fluids and temperatures.

Wedge Wire Screen Types and Configurations

Wedge Wire Screen Types:

Panel shape wedge wire screen – used in vibrating screens, dewatering screens, and sizing applications.

Cylinder shape wedge wire – ideal for rotary screens, drum screens, and centrifugal filter applications.

Wedge wire grids – custom fabricated support grids for filter media, laterals, and underdrain systems.

Wedge wire screen sieves – precision sieves used in laboratory and industrial particle sizing.

Additional configurations include sieve bend screens, lateral screens, hub and header systems, and filter nozzles. Each type can be manufactured to exact customer specifications regarding slot size, wire thickness, open area percentage, and overall dimensions.

Key Applications Across Industries

Beyond these core applications, wedge wire screens are also employed in hydrocyclones, centrifuges, belt presses, and as retention screens in anaerobic digesters. Their durability and precision make them a preferred choice for industries requiring consistent separation efficiency and low maintenance.
