Precision Wedge Wire Screens: ndustrial Solutions​

Core Technology Principles

Wedge wire screens utilize V-shaped wires laser-welded to support rods, creating precision filtration surfaces. The 35° wire angle minimizes turbulence. Slot tolerance reaches ±0.003mm. Under 1,500 psi cyclic pressure , weld failure rate is <0.01%, far superior to woven screens.

Industry-Specific Solutions

Water Treatment: 45° angled panels reduce algae clogging by 70% .

Mining: Tungsten carbide-coated rods extend service life 3X in copper tailings.

Pharma: 0.001" slots meet FDA CFR 211.65 for API purity >99.97% .

Material Corrosion Resistance

In 20% HCl environment:

• 316L SS: 0.5 mm/year corrosion rate

• Hastelloy C-276: 0.02 mm/year corrosion rate
  For high-temperature applications (>150°C), 310S alloy withstands 5,000-hour salt spray. Electropolished surfaces (Ra≤0.4μm) are mandatory for food/pharma to eliminate microbial adhesion.

Our screen can be welded to nipples, couplings, pipe, or flanges.

Our Wedge Wire Screen is designed to control various processing conditions including volumetric flow rate, minimum dimensional media retention, minimum open area and fluid pressure capabilities.

The fabricated and welded construction makes for durable quality vessel internals and media retention products. Wire mesh and perforated pipe may be less expensive initially, but wedge wire screens offer easier installation and long-term operating and cost benefits. Any process or vessel requirements can be accommodated, such as vertical or horizontal vessels.
