Wire Mesh Cylindrical Filters
Wire Mesh Cylindrical Filters | Custom SS304/316L Woven Filter Tubes
Wire Mesh Cylindrical Filters are the foundational elements of industrial filtration, constructed by forming woven metallic cloth into a cylinder. The manufacturing process involves precision rolling followed by seam joining using resistance welding, plasma welding, or ultrasonic welding to ensure structural integrity. Unlike simple strainers, these filters utilize advanced weave patterns (such as Dutch or Reverse Dutch weave) to achieve specific geometric pore structures, providing a balance between flow rate and particle capture efficiency.
Advantages of Wire Mesh Cylindrical Filters
- Precise Surface Filtration: Offers straightforward, absolute (nominal) particle retention based on the mesh aperture size.
- High Structural Integrity: The woven mesh and welded seam provide excellent resistance to collapse and fatigue under pulsating or differential pressure.
- Material Versatility: Available in a wide range of alloys to meet specific corrosion, temperature, and sanitary requirements.
- Reusability & Sustainability: Designed for multiple cleaning cycles, reducing long-term operational waste and cost.
- Design Flexibility: Easily integrated into existing systems via various end connections and can be customized with flanges, caps, or handles.
Specification of Wire Mesh Cylindrical Filters
- Primary Materials: AISI 304 (general purpose), AISI 316/L (corrosive/chloride environments), Duplex (high strength/corrosion), Nickel alloys (Monel, Inconel for high temp/acid), Brass, Phosphor Bronze.
- Weave Patterns:
- Plain/Square Weave: Most common, for general filtration.
- Twill Dutch Weave: For finer micron ratings, offers high strength and stable pore size.
- Reverse Dutch Weave: For high flow and excellent cake release.
- Construction: Seam is typically tungsten inert gas (TIG) welded for permanence and strength. Alternative locking methods exist for non-critical applications.
- Filtration Rating: 1 μm (fine Dutch weaves) to 5000 μm (coarse screens). Rating can be expressed as mesh count (e.g., 100×100 mesh) or absolute/nominal micron.
- Standard Dimensions: Outer Diameter (OD): 10 mm to 500 mm; Length: 10 mm to 1500 mm. Larger custom sizes are manufacturable.
- End Connections: Male/Female NPT/BSP/UN threads, DIN/ISO flanges (e.g., DN50, DN100), quick-disconnect fittings, or custom weld-ready ends.
Applications of Wire Mesh Cylindrical Filters
- Polymer Filtration: Spin packs, melt streams, and gear pumps.
- Hydraulic & Lube Oil Systems: Suction and return line protection.
- Water & Wastewater: Intake screens, filter housings, and irrigation.
- Food & Beverage: Sugar syrup, cooking oil, beer, and wine.
- Chemical Processing: Solvent filtration, catalyst recovery, vent filters.
