Wedge Wire Screens for Chemical Processing

Chemical processing operations require filtration and separation equipment that withstands aggressive chemicals, elevated temperatures, and continuous duty cycles. Wedge wire screens serve as catalyst support grids, reactor internals, and process filtration elements across fertilizer production, polymer processing, paint and coating manufacturing, and specialty chemical plants. The non-clogging V-wire profile and resistance to thermal cycling make wedge wire the preferred screening solution where process purity and equipment uptime are non-negotiable.

APPLICATIONS

Where Our Screens Work

Catalyst Retention and Support

Cylindrical and flat wedge wire screens serve as catalyst bed supports in fixed-bed and moving-bed reactors. Precise slot sizing retains catalyst particles while allowing reactant flow, preventing catalyst loss and downstream contamination.

Reactor Internals

Custom-engineered wedge wire elements function as distribution plates, collection headers, and separation internals inside chemical reactors. Resistance to thermal cycling and chemical attack ensures long service life.

Chemical Filtration

Process filtration screens for removing solid contaminants from liquid chemical streams. Applications include fertilizer slurry filtration, polymer melt screening, and paint pigment classification.

Fertilizer Production

Screens for granulation, sizing, and classification of urea, ammonium nitrate, and NPK fertilizer products. Corrosion-resistant grades handle acidic and alkaline process conditions.

Polymer and Resin Processing

Fine-slot screens for polymer pellet dewatering, resin bead classification, and melt filtration in plastics manufacturing.

Resin Traps

In-line wedge wire strainer baskets capture migrated ion exchange resin and protect downstream pumps, valves, and instruments.

Support Grids

Wedge wire support grids retain catalyst, adsorbent, and packing media above bed gratings in fixed-bed reactors and columns.

Distributor and Collector Systems

Inlet distributors and outlet collectors in radial- and axial-flow vessels — even fluid distribution across packed beds.

Gas-Liquid Contactors

Wedge wire trays and packing supports for absorption, stripping, and reactive distillation columns.

FAILURE MODES & MITIGATION

How Screens Fail — and How We Prevent It

Aggressive chemical attack

Material grade selected per service chemistry — SS 316L baseline through Super Duplex; Hastelloy, Inconel, Titanium, or Monel for special-project specifications.

Thermal shock and creep

316Ti and 321 stabilized grades resist carbide precipitation in temperature-cycling reactors. Continuous-weld construction tolerates thermal expansion.

Catalyst dust accumulation

Slot opening matched to the smallest catalyst fraction with safety factor. V-wire profile releases dust during reverse-flow or thermal cycling.

Crevice corrosion at supports

Resistance-welded V-wire to support bars eliminates the crevices that cause localized attack in welded mesh and bar-rack designs.
