Silicone Coated Dust Bag Cages

Silicone Coated Dust Bag Cages

Silicone Coated Dust Bag Cages Oveview

Silicone Coated Dust Bag Cages are high-strength steel support cages treated with a high-temperature silicone layer to protect both the cage and the filter bag. Engineered for demanding dust-collection systems where condensation, corrosive off-gases, or adhesive particulates are present, silicone coated cages offer longer service life and more stable differential pressure than uncoated carbon-steel designs.

Key Selection Criteria

  • Base cage material
    • Low-carbon steel – economic choice for standard conditions
    • Stainless steel (SS304 / SS316L) – for higher temperature or more aggressive chemistry
  • Silicone coating characteristics
    • Uniform exterior and interior coverage (wires, rings, welds, collars)
    • Smooth, non-sticky surface to improve dust release and reduce bag abrasion
    • Enhanced resistance to moisture, light acids/alkalis, and cold-end corrosion
  • Mechanical specifications
    • Wire diameter: typically 3.0–5.0 mm, selected according to cage height and bag weight
    • Vertical wires: 8 / 10 / 12 / 16 / 20 / 24 for the required rigidity
    • Ring spacing: 6″ or 8″ to balance airflow stability and fabric support
    • Cage shapes: Round, oval, diamond, pleated/star to match baghouse layout and air-to-cloth ratio
  • Connection & compatibility
    • Designed for snap-band, sew-in or cuff-type filter bags
    • Optional venturi, collar and joint designs to suit existing tube sheet and cleaning system
    • Tolerances controlled for diameter, straightness and ring alignment to avoid bag wear points

INDUSTRIAL
APPLICATIONS

Engineered for high-temperature, corrosive, abrasive, and heavy-dust industrial environments,Silicone Coated filter bag cages deliver exceptional structural stability, long service life, and consistent filtration performance.

More Applications
Cement, Lime & High-Dust Baghouse Filtration

Cement, Lime & High-Dust Baghouse Filtration

Stainless steel cages are the preferred choice for cement kilns, clinker coolers, lime kilns, and preheater towers due to their ability to withstand: constant high dust loading, abrasive particles, elevated operating temperatures, continuous pulse-jet impact.

Steel Plants, Metallurgy & Foundry Exhaust Systems

Steel Plants, Metallurgy & Foundry Exhaust Systems

Ideal for steel mills and metallurgical operations where flue gas contains corrosive fumes, high-temperature particulates, and sparks. Stainless steel cages offer: excellent resistance to oxidizing and acidic gas, stable structural support under thermal cycling, minimized risk of deformation during heavy pulse cleaning.

Waste-Incineration, Power Generation & Chemical Processing

Waste-Incineration, Power Generation & Chemical Processing

Stainless steel cages maintain mechanical strength even under extreme pH, moisture, and temperature conditions. Their smooth welded finish reduces abrasion, helping improve bag performance and lower total operating cost (TOC).

Pre-Project Technical Evaluation

  • Analyze dust chemistry, condensation risk, and corrosion level to decide if silicone coating is required.
  • Select base cage material: low-carbon steel for standard duty or SS304/SS316L for higher temperature and aggressive gases.
  • Evaluate particle size, dust loading, stickiness, and pulse-jet cleaning intensity.
  • Check compatibility with bag type (snap-band, sew-in, cuff), bag diameter/length, and venturi/collar design.
  • Review temperature profile, dew point approach, and expected service life targets.

Custom Engineering Solutions

  • Cage shapes: round, oval, diamond, pleated/star to match baghouse layout and air-to-cloth ratio.
  • Mechanical options: wire diameter 3.0–5.0 mm; vertical wires 8–24; ring spacing 6″ or 8″.
  • Silicone coating applied to wires, rings, welds and collars for full exterior/interior coverage.
  • Surface engineered to be smooth and non-sticky, improving dust release and reducing fabric abrasion.
  • Custom venturi, collar and joint designs available to fit existing tube sheet and cleaning system.

Quality Assurance & Testing

  • Coating adhesion and thickness tests to ensure long-term protection of steel and filter bag.
  • Visual and tactile inspection for pinholes, bare spots, runs and sharp burrs.
  • Moisture, light acid/alkali and cold-end corrosion resistance verification.
  • Dimensional checks: cage diameter, straightness, ring spacing and wire alignment.
  • Airflow and pressure-drop performance checks to confirm stable filtration efficiency after coating.
