ASTM A213 T22 HFW Serrated Finned Tube With Carbon Steel Fins For Furnace
ASTM A213 T22 HFW Serrated Finned Tube with Carbon Steel Fins is a specialized type of heat exchanger tube designed for high-efficiency thermal transfer in boilers, superheaters, and other high-temperature/pressure applications. Here’s a detailed breakdown of its components and characteristics:
1. Base Tube Specifications
(1) Chemical Composition (Weight %)
| Element | ASTM A213 T22 Requirements | Typical Values |
| Carbon (C) | 0.05–0.15% | 0.10% |
| Manganese (Mn) | 0.30–0.60% | 0.45% |
| Phosphorus (P) | ≤ 0.025% | 0.015% |
| Sulfur (S) | ≤ 0.025% | 0.010% |
| Silicon (Si) | ≤ 0.50% | 0.25% |
| Chromium (Cr) | 1.90–2.60% | 2.25% |
| Molybdenum (Mo) | 0.87–1.13% | 1.00% |
| Iron (Fe) | Balance | Balance |
Notes:
Key Alloying Elements: Cr and Mo provide oxidation resistance and high-temperature strength.
Low S/P: Minimizes hot cracking during welding.
(2) Mechanical Properties
| Property | ASTM A213 T22 Requirements | Typical Values |
| Tensile Strength | ≥ 415 MPa (60 ksi) | 450–550 MPa |
| Yield Strength (0.2% offset) | ≥ 205 MPa (30 ksi) | 240–300 MPa |
| Elongation (in 50 mm) | ≥ 30% (for longitudinal) | 35–40% |
| Hardness (Brinell) | ≤ 163 HBW | 140–160 HBW |
Additional Requirements:
Heat Treatment:
T22 tubes are typically supplied in the normalized and tempered condition (e.g., 900–950°C normalized, 680–730°C tempered).
High-Temperature Performance:
Creep Strength: ~34 MPa at 600°C (1,112°F) for 100,000 hours.
Oxidation Resistance: Stable up to 580°C (1,076°F) in steam environments.
(3) Key Applications
2. Fin Design
Fin Type: Serrated Fins
Key Benefits:
3. Comparison to Alternatives
| Feature | ASTM A213 T22 HFW Serrated Finned Tube | Smooth-Finned Tube | Extruded Finned Tube |
| Heat Transfer | Highest (serrations create turbulence) | Moderate | High (but no serrations) |
| Cost | Mid-range (HFW + carbon steel fins) | Lowest | Highest (extrusion process) |
| Durability | Excellent (T22 + welded fins) | Good | Excellent (monolithic) |
4. Key Considerations for Buyers
Fin Density: Typically 5-11 fins per inch (FPI), depending on gas flow requirements.
Corrosion Protection: Optional aluminization or ceramic coating for harsh environments.
Customization: Fin height, thickness, and serration pattern can be tailored
The ASTM A213 T22 HFW Serrated Finned Tube with Carbon Steel Fins is a high-performance heat transfer component designed for demanding industrial applications. Here’s a detailed breakdown of its key applications and advantages:
1.Primary Applications
A. Power Generation
B. Oil & Gas/Petrochemical
C. Industrial Heat Exchangers
D. HVAC & Energy Recovery
2. Why Choose This Combination?
| Feature | Benefit |
| ASTM A213 T22 Base Tube | High-temperature strength, corrosion resistance, and weldability. |
| HFW (High-Frequency Welded) | Cost-effective for mass production; weld integrity comparable to seamless. |
| Serrated Carbon Steel Fins | 20–30% higher heat transfer vs. smooth fins; resistant to thermal fatigue. |
| Carbon Steel Fins | Economical, compatible with T22 base metal, and easily weldable. |
