ASTM A213 T9 Solid Fin Tube For Furnances and Superheaters

ASTM A213 T5 Solid Fin Tube Application

• Boilers & Superheaters – Used in power plants for efficient steam generation.
• Heat Recovery Steam Generators (HRSGs) – Recovers waste heat from gas turbines.
• Petrochemical & Refinery Heaters – Handles high-temperature hydrocarbon processes.
• Furnace & Convection Sections – Enhances heat transfer in industrial heaters.
• Waste Heat Boilers – Recovers energy from exhaust gases.

ASTM A213 T5 Solid Fin Tube FAQ

1. What is ASTM A213 T5 Solid Fin Tube?

• A seamless ferritic alloy-steel tube with externally welded or extruded solid fins for enhanced heat transfer.
• Material: ASTM A213 T5 (5Cr-0.5Mo alloy steel), offering good high-temperature strength and oxidation resistance (up to ~600°C / 1112°F).

2. Key Features & Benefits

• High-Temperature Performance: Resists scaling and creep in boilers, heaters, and reformers.
• Corrosion Resistance: Suitable for sulfur-rich or mildly corrosive environments.
• Efficient Heat Transfer: Solid fins increase surface area by 3–10x vs. bare tubes.
• Durable Construction: Fins are welded (HFW or GTAW) or cold-formed for longevity.

3. ASTM A213 T5 vs. T9 vs. T11 Comparison

4. Standards & Certifications

• ASTM A213: Covers seamless alloy-steel boiler tubes.
• ASME SA213: Equivalent for pressure vessel compliance.
• NACE MR0175: For sour service (if applicable).
• Dimensional Standards: ANSI/ASME B36.10 (tube sizes).

5. FAQs
Q1: Can A213 T5 fin tubes handle high-pressure steam?

• Yes, but T9/T11 are better for >600°C. T5 is ideal for moderate-pressure boilers (~1500 psi).

Q2: How do solid fins compare to serrated fins?

• Solid fins: Higher durability, better for dirty/corrosive gases.
• Serrated fins: Higher heat transfer but prone to fouling.

Q3: Are these tubes weldable?

• Yes, but requires pre/post-weld heat treatment (PWHT) to avoid cracking.

Q4: How to prevent fin oxidation?

• Use aluminized or ceramic-coated fins for >500°C service.
