Wedge wire screen engineering guide
A comprehensive reference for sizing slot openings, selecting wire profiles, evaluating support structures, and calculating flow orientation across industrial separation systems.
1. Slot Opening & Open Area Calculation
Continuous slot widths define particle cutoff, hydraulic capacity, and differential pressure.
| Slot Opening (mm / µm) | Imperial (Inches) | Recommended Wire Profile | Typical Open Area | Typical Industrial Service |
|---|---|---|---|---|
| 0.020 mm (20 µm) | 0.0008 in | 12S / 18S | 8% – 14% | Fine resin traps, catalyst retention, micro-straining |
| 0.050 mm (50 µm) | 0.0020 in | 18S / 22S | 15% – 24% | Water filtration, pharmaceutical separation, edible oil polish |
| 0.100 mm (100 µm) | 0.0040 in | 22S / 28S | 22% – 35% | Intake screens, brewing mash tuns, pulp recovery |
| 0.250 mm (250 µm) | 0.0100 in | 28S / 34S | 32% – 48% | Cooling tower strainers, sand retention, mineral slurries |
| 0.500 mm (500 µm) | 0.0200 in | 34S / 42S | 42% – 60% | Dewatering screens, trommels, vibrating screen decks |
| 1.000 mm (1000 µm) | 0.0394 in | 42S / 60S | 52% – 72% | Coarse solids separation, grain screening, trash racks |
Ideal for ultra-fine slots where open area must be preserved without restricting fluid paths.
The versatile standard for liquid-solid separation, vessel internals, and screen tubes.
Designed for high-differential pressure services, abrasive slurries, and mechanical rakes.
Maximum impact and wear resistance for heavy mining, vibrating shakers, and rotary trommels.
Advantage: Low hydrodynamic drag and balanced radial support for standard screen tubes.
Common Application: Water well casing, cartridge elements, and standard cylindrical screen baskets.
Advantage: Superior beam stiffness along the flow axis for flat panels and vibratory screens.
Common Application: Dewatering panels, static sieve bends, and high-impact vibratory decks.
Advantage: Minimizes backpressure and flow stagnation behind support junctions.
Common Application: High-velocity radial flow reactors and gas-solid catalyst bed support grids.
4. Flow Direction & Construction Geometry
Wedge wire cylinders and screen tubes are configured in either standard or inverted orientation depending on the filtration mechanism.
Smooth External Surface with Internal Support Rods
In the standard configuration, the flat faces of the profile wire wrap circumferentially around axial support rods on the interior. Debris is retained on the outer smooth surface, while clean filtrate travels through the inward-widening slots into the central core.
Manufactured with precision resistance welding. Available with threaded fittings, weld rings, or custom flange terminations.
5. Metallurgy & Material Selection Matrix
Matching alloy grade to operating chemistry, chloride concentrations, temperature, and mechanical stress.
AISI 304 / 304L
Standard atmospheric, fresh water, and general organic chemicals.
AISI 316 / 316L
High resistance to pitting and crevice corrosion in chloride-bearing media.
Duplex 2205 (UNS S32205)
Twice the yield strength of 316L with high stress-corrosion cracking resistance.
Hastelloy C-276 / Alloy 20
Extreme resistance to strong acids, wet chlorine, and sour hydrocarbon streams.
