Component Specifications

Definition
Support rings are circular or polygonal structural elements integrated into filter bag cages, typically positioned at intervals along the cage height. They provide radial support to filter bags, preventing bag deformation, collapse, or contact with adjacent bags during operation. These rings ensure consistent filtration surface area, optimize dust cake formation, and extend bag life by reducing mechanical stress.
Working Principle
Support rings work by providing rigid circumferential support to the filter bag fabric. During filtration cycles, differential pressure across the bag can cause inward collapse; the rings resist this force, maintaining an open flow path for dirty gas and preventing bag-to-bag contact. During cleaning cycles (pulse-jet or reverse air), they help the bag flex properly for effective dust dislodgement without excessive stress.
Materials
Typically carbon steel (ASTM A36), stainless steel (304/316L for corrosion resistance), or galvanized steel. Wire diameter: 4-8 mm. Surface treatments may include powder coating, epoxy coating, or hot-dip galvanizing for environmental protection.
Technical Parameters
  • Shape Circular, octagonal, or hexagonal
  • Spacing 300-600 mm between rings
  • Welding Continuous weld or spot weld to cage verticals
  • Diameter 100-300 mm (matches bag/cage diameter)
  • Load Capacity 10-50 kg radial load (depends on material)
  • Wire Thickness 4-8 mm
Standards
ISO 2942, DIN 2458

Frequently Asked Questions

What happens if support rings fail in a filter bag cage?

Failure can cause bag collapse, reduced filtration area, increased pressure drop, bag abrasion from contact, and premature bag replacement, leading to system inefficiency and downtime.

Can support rings be replaced separately from the cage?

Yes, if welded, they can be cut and rewelded, but replacement often requires partial cage disassembly. Some designs use removable rings for easier maintenance.

How do I select the right material for support rings?

Choose based on operating environment: carbon steel for dry, non-corrosive conditions; stainless steel for moisture, chemicals, or high temperatures; galvanized steel for moderate corrosion resistance.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
