Explosion-Proof & Anti-Static flexible Duct Ultimate Guide
Ⅰ. Critical Challenges in High-Risk Industries: Why Conventional Ducts Fail
1.1 Global Safety Alerts
Chemical Plant Explosions: 2023 ITCO (International Tank Container Organization) report indicates static ignition causes 23% of hazardous material incidents
Mining Disaster Analysis: Chile Copper Mine study shows metal duct sparks triggered 17% of methane explosions in 2010-2023
1.2 Three Fatal Flaws of Traditional Solutions
Fire Spread Risk: Standard PVC melts at 80°C with flaming drips
Static Accumulation: Surface resistivity >10¹²Ω generates 8,000V+ in powder transfer
Structural Failure: Galvanized steel rings deform by 41% under 0.3MPa negative pressure
Ⅱ. Triple Defense System Breakdown: Engineering Absolute Safety
2.1 Layer 1: Class B Fire Armor
AS/NZS 1530:2022 Certification Highlights:
Vertical burn test: Self-extinguishing within 3s (vs. >30s for PVC)
Zero ignition of cotton pad by molten drops
Stable performance from -30°C to +120°C
2.2 Layer 2: Static Dissipation Network
IEC 62631 Compliance:
Surface resistivity: 10⁴-10⁶Ω (Meeting ISO 8031:2020 Level A)
Charge decay: <2s (Field test data from global sites)
| Scenario | Conventional Duct | Our Solution |
| Powder Handling | 15kV | 0.3kV |
| Gas Exhaust | 8kV | 0.1kV |
| Equipment Friction | 12kV | 0.5kV |
2.3 Layer 3: Mechanical Fortress
Military-Grade Spring Steel Skeleton:
High-carbon steel tensile strength: ≥1,500MPa (3× standard alloys)
100,000 bending cycles with zero structural failure
