Stainless Steel Snap Bands and Elastic Strips for Filter Bags and Industrial Sealing

Stainless Steel Snap Bands and Elastic Strips for Filter Bags and Industrial Sealing

How to Choose the Right Snap Band Material for Filter Bags

Snap Band Elasticity, Strength, and Anti-Deformation Requirements

Snap bands (aka snap rings) secure filter bags on the tube-sheet and provide a reliable seal during pulse-jet cleaning.
To perform reliably, the snap band must maintain the correct balance between elasticity and strength:

• If the band is too soft, it creases easily and loses springback.

• If the band is too rigid, it may crack after repeated compression cycles.

A Qualified Snap Band Should:

• Withstand repeated flattening during installation without cracking
• Return to a uniform circular shape after compression (not become oval)
• Maintain stable sealing force during long-term operation
• Resist deformation under vibration and thermal cycling

A high-quality snap band can be flattened during installation and will return to a perfect circular shape after release — without cracking and without becoming oval.

Stainless Steel Snap Bands: Material Selection Guidelines

• Select stainless steel with stable elastic recovery, not just “high hardness”
• Ensure controlled work-hardening during forming to prevent brittleness
• Control width and thickness tolerances to ensure consistent sealing fit

Product Overview

KABORY stainless steel snap bands are engineered for high-performance filter bag systems, providing long-term elasticity, reliable clamping force, and stable sealing performance.

Each coil is precision-slitted and bright-annealed to ensure:

• Smooth edges

• Uniform tension

• Consistent springback

• No flattening or oval deformation during repeated installation cycles

Available Material Options

Material	Key Feature	Suitable Applications
SUS301	High elasticity & strong clamping force	Standard and high-vibration dust collectors
SUS316L	Superior corrosion resistance	Chemical plants, food, waste-to-energy, high-humidity systems

KABORY snap bands integrate seamlessly with automatic welding and riveting systems, ensuring:

• Stable feeding

• Accurate alignment

• Continuous production

• Zero deviation in modern filter bag manufacturing lines

 Fiberglass Filter Bags &High temperature Filter Bags & Corrosive Environments

Fiberglass filter bags are prone to edge wear and tearing.

For these demanding applications, SUS316L snap bands are the preferred choice:

• Outstanding corrosion resistance against acid gases and moisture-laden environments

• Reliable sealing under high heat and vibration

• Polished bright-annealed finish to minimize abrasion

By contrast, SUS301 provides superior elasticity and is ideal for most dust collection applications.
However, in aggressive chemical or high-humidity environments, it may suffer from corrosion or reduced clamping force.
To address this industry challenge, KABORY developed SUS316L snap bands as a dedicated solution for long-term sealing performance — eliminating failure risks where standard 301 grades cannot perform.

⚠️ Automation Compatibility Matters

Most steel band suppliers overlook a critical factor: flatness and consistency across the roll.

Even minor deviations such as:

• ⚠️ Wave distortion or edge curling
• ⚠️ Thickness variation
• ⚠️ Burrs or slitting defects
  can result in:

⚠️ Misaligned feeding or jammed rollers
⚠️ Welding or riveting failures
⚠️ Mold seizure or tooling breakdowns
⚠️ Increased downtime and maintenance cost

A snap band may seem insignificant, but poor strip quality can halt an entire production line or compromise bag sealing during pulse-jet cleaning.

High springback also mitigates permanent set from repeated assembly, improving yield and consistency on automated riveting/welding lines.

📌 Case Study: The Real Cost of Poor-Quality Snap Bands

At first glance, a snap band may seem like a small, inexpensive component in the overall filter bag system. But when quality is compromised, the consequences are significant:

• Leakage & Dust Emissions
  Inferior snap bands often suffer from poor flatness, inconsistent hardness, or rough edges. This leads to incomplete sealing against the tube sheet, causing dust to leak into clean air chambers.

• Bag Slippage & Unexpected Drop-Off
  Weak bands lose their clamping force under vibration or pulse-jet cleaning. In extreme cases, entire filter bags can loosen or fall from the tube sheet — leading to unplanned shutdowns and severe safety risks.

• Accelerated Filter Bag Wear
  Snap bands with burrs or uneven surfaces can cut into the filter bag cuff, shortening the service life of bags that are otherwise designed to last years.

• Hidden Costs Outweigh “Savings”
  While low-cost snap bands may save a few dollars per coil, the cost of replacing prematurely failed bags — or worse, dealing with production downtime and environmental penalties — far outweighs the initial “savings.”

💡 When compared with the cost of filter bags themselves (often hundreds of dollars per bag) or the operational losses from unscheduled maintenance, investing in precision-engineered stainless steel snap bands is the only rational choice.

We maintain tight tolerances on material flatness, edge finish, and mechanical properties to ensure compatibility with automated production lines.

Beyond Filter Bags – Extended Applications

KABORY stainless steel strips are widely used for:

• Industrial sealing rings and clamps

• Pneumatic conveying couplings

• Flexible duct connectors (e.g., BFM-style systems)

• Elastic fastening components in chemical, power, and process industries

Wherever resilience, clamping strength, and corrosion resistance matter, KABORY stainless steel provides proven reliability.

 Snap Band Selection Tips

1. Corrosion Exposure: Use SUS316L in acid/alkaline or chloride-rich conditions
2. Machine Type: Confirm compatibility with your automatic snap band  riveting machine or Automatic Snap  Band Welding  Machine
3. Bag Size Fit: Match snap band width/thickness to bag diameter and groove depth
4. Media Type: Choose bright-annealed finish for laminated or fiberglass bags
5. Reliability: Select vendors who understand automation—not just metallurgy
