Anping CREMOTIVE Wire Mesh Products CO., LTD’s reverse plain Dutch weave wire mesh combines fine cross-wires with coarser longitudinal wires to form slotted openings suited for high-precision filtration. In “reverse” configuration, the finer wires run in the weft direction, creating elongated rectangular slots that resist deformation and maximize open area for efficient fluid flow.
Weave Structure & Materials
Wire Combination: Fine weft wires (as small as 0.03 mm diameter) interwoven with heavier warp wires (0.3 mm to 1.0 mm). The resulting slots measure from 10 µm × 80 µm up to 200 µm × 2000 µm.
Crimping & Stability: Each intersection is crimped twice—once for each wire direction—locking wires firmly in place and preventing migration under pulsating flow.
Alloy Selection: Standard 316L stainless steel for corrosion resistance; specialized alloys (e.g., duplex stainless or Inconel) available for extreme chemical or temperature service.
Performance Attributes
High Open-Area (35 %–45 %): Maximizes throughput and reduces pressure drop across the mesh, critical in membrane pretreatment and catalyst recovery.
Uniform Slot Precision: Tolerances of ±10 % for sub-50 µm slots maintain consistent cut-points in fine filtration tasks.
Mechanical Strength: Heavy warp wires carry structural loads, allowing large unsupported mesh panels in pressure vessels and cartridges without backing support.
Applications
Pharmaceutical Production: Clarification of fermentation broths and sterile venting in bioreactors, where slot uniformity ensures repeatable performance.
Fine Chemical Processing: Catalyst separation and recovery in hydrogenation and polymerization reactors.
Membrane Pretreatment: Protecting RO and UF membranes from particulate fouling in water treatment and desalination.
Industrial Gas Filtration: Particulate removal in compressed-air dryers and flue-gas cleaning systems.
Customization & Quality Assurance
Anping CREMOTIVE produces reverse plain Dutch weave mesh in rolls up to 2 m wide and panel sizes up to 6 m². Crimp patterns, wire diameters, and alloy grades are tailored per customer specifications. Each production lot undergoes optical slot measurement, porosity testing, and flow-through validation under simulated operating conditions. Passivation treatments conform to ASTM A967 to ensure a stable, protective oxide layer.
Installation & Maintenance
Mesh panels may be installed directly into cartridge housings or laser-cut and edged for filter plates. Cleaning is conducted via backflushing, ultrasonic baths, or chemical soaking, with recommended protocols provided in our technical manuals. Proper handling and storage in a dry environment prevent contamination and preserve mesh geometry prior to use.
