The HFW Serrated Alloy Fin Tube is a high-performance heat transfer component designed for demanding industrial applications. It combines the superior mechanical properties of ASME SA335 P9 alloy steel with the enhanced heat transfer efficiency of carbon steel strip fins. The serrated fin design maximizes surface area, making it ideal for high-temperature and high-pressure environments such as boilers, heaters, and heat recovery systems.
The tube and fin materials are carefully selected to ensure optimal performance:
| Component | ASME SA335 P9 Tube | Carbon Steel Strip Fins |
|---|---|---|
| Carbon (C) | 0.15% max | 0.10–0.25% |
| Manganese (Mn) | 0.30–0.60% | 0.30–0.90% |
| Silicon (Si) | 0.50–1.00% | ≤0.10% |
| Chromium (Cr) | 8.00–10.00% | – |
| Molybdenum (Mo) | 0.90–1.10% | – |
| Phosphorus (P) | 0.025% max | ≤0.04% |
| Sulfur (S) | 0.025% max | ≤0.05% |
Key Features of Materials:
ASME SA335 P9: High chromium-molybdenum content provides excellent resistance to oxidation, creep, and high-temperature corrosion.
Carbon Steel Strip: Cost-effective and durable, with good thermal conductivity for efficient heat transfer.
Enhanced Heat Transfer:
The serrated fin design increases the surface area by up to 10–15 times compared to bare tubes, significantly improving heat exchange efficiency.
High-Temperature Performance:
The ASME SA335 P9 base tube can withstand temperatures up to 600°C (1112°F), making it suitable for extreme environments.
Corrosion Resistance:
The chromium-molybdenum alloy provides excellent resistance to oxidation and sulfidation, extending the tube's service life.
Mechanical Strength:
High tensile strength and creep resistance ensure reliable performance under high-pressure conditions.
Cost-Effective:
The use of carbon steel fins reduces overall material costs while maintaining high thermal efficiency.
The HFW Serrated Alloy Fin Tube is widely used in industries requiring efficient heat transfer under harsh conditions:
Power Generation:
Boilers, superheaters, and economizers in coal-fired and gas-fired power plants.
