Common Faults & Troubleshooting
1. Elastic Failure/Loosening
- Causes: Long-term high temperature, fatigue aging, material degradation, overstress
- Symptoms: Loose pipes, air/fluid leakage, vibration noise, pressure drop
- Solution: Replace C3926702; check diameter matching, avoid over-expansion
2. Breakage/Unhooking
- Causes: Improper installation, forced twisting, material defects, repeated disassembly
- Symptoms: Clamp fracture, deformed lugs, pipe detachment, seal failure
- Solution: Replace genuine clamp; use proper tools, maintain symmetrical force
3. Rust/Coating Peeling
- Causes: Moisture, salt spray, chemical corrosion, coating damage
- Symptoms: Surface rust, jamming, reduced elasticity, pipe contamination
- Solution: Replace galvanized clamp; keep installation area dry and clean
4. Poor Sealing/Leakage
- Causes: Incorrect size, aged rubber seal, improper installation, dirty surfaces
- Symptoms: Interface seepage, unstable pressure, performance degradation
- Solution: Verify specifications, clean interfaces, replace seals, tighten correctly
