Stainless Steel Corrugated Fin Tubes
Stainless steel corrugated finned tubes are highly efficient heat transfer components that significantly enhance thermal performance through their unique wave-like fin design. Key structural features and advantages include:
I.Stainless Steel Corrugated Fin Tube Core Structure & Heat Transfer Principle
- Base Tube Material
- Made of stainless steel grades (e.g., 304, 316, 321), offering corrosion resistance (tolerates pH 2–11 media) and high-temperature endurance (up to 800°C) .
- Corrugated Fin Design
- Fins feature wave-like or spiral corrugations, bonded to the base tube via high-frequency welding or mechanical rolling .
- Typical fin height: 2–15 mm; spacing: 2–8 mm; heat transfer area: 8–15× that of bare tubes.
- Enhanced Heat Transfer
- Corrugations disrupt laminar boundary layers, boosting turbulence and increasing heat transfer efficiency by >40% compared to straight fins .
II.Stainless Steel Corrugated Fin Tube Performance Advantages
- High-Efficiency Heat Exchange
- Corrugated fins increase flue gas-side convective heat transfer coefficient by 60%, reducing exhaust temperatures to ≤120°C .
- Superior Corrosion Resistance
- 316L stainless steel withstands sulfur-containing flue gases for >10 years, ideal for chemical/marine environments .
- Anti-Fouling Design
- Wave-induced turbulence minimizes dust accumulation; paired with ≥8 m/s flue gas velocity for enhanced prevention .
III.Stainless Steel Corrugated Finned Tube Typical Applications
Industry | Application Scenario | Technical Adaptation |
---|---|---|
Industrial Boilers | High-temp flue gas heat recovery | 316L material + spiral corrugated fins (650°C rated) |
Chemical Equipment | Corrosive media heat exchange | Corrugated fins resist acid dew point corrosion |
Food/Pharmaceutical | Sterilization/drying systems | 304 material meets sanitary standards |
Agricultural Greenhouses | Climate control | Wave structure optimizes airflow disturbance |
IV.Stainless Steel Corrugated Finned Tube Selection & Maintenance Guidelines
- Quality Control: Welded fin joints must be pore-free; contact thermal resistance ≤0.02 m²·K/W .
- Layout Specification: Staggered arrangement requires tube spacing ≥2× fin height to prevent dead zones .
- Maintenance: Coal-fired systems: clean every 3 months; gas-fired systems: inspect corrosion every 6 months .
⚙️ Summary: Corrugated finned tubes balance efficiency and durability through structural innovation, making them the optimal solution for extreme thermal management scenarios .
