Description

Serrated Fin Tube, High Frequency Welding Tube, ASTM A213 T11, For Furnace and Heater


Overview

The Serrated Fin Tube made from ASTM A213 T11 alloy steel and fabricated via High Frequency Welding (HFW) is specifically engineered for high-temperature applications such as furnaces and industrial heaters. The serrated fin structure maximizes turbulence and heat transfer efficiency, making it a superior choice for heat recovery and fuel efficiency in power plants, petrochemical refineries, and thermal processing units.

Element Content (%)
Carbon (C) 0.05 – 0.15
Manganese (Mn) 0.30 – 0.60
Phosphorus (P) ≤ 0.025
Sulfur (S) ≤ 0.025
Chromium (Cr) 1.00 – 1.50
Molybdenum (Mo) 0.44 – 0.65

2. Mechanical Properties – ASTM A213 T11

Property Value
Tensile Strength ≥ 415 MPa
Yield Strength ≥ 205 MPa
Elongation ≥ 30%
Hardness ≤ 85 HRB

3. Fin Characteristics – Serrated Fin

Property Value/Range
Fin Type Serrated
Material Carbon Steel
Fin Thickness 0.8 – 2 mm
Fin Height 10 – 30 mm
Fin Pitch 5 – 10 mm
Welding Method High Frequency Welding

4. Key Advantages

  • Increased surface turbulence enhances thermal performance significantly over plain fins.

  • High structural integrity from HFW process ensures tight fin-to-tube bonding.

  • Excellent resistance to oxidation and creep under continuous high-temperature conditions.

  • Longer service life, even in aggressive flue gas or fuel-rich atmospheres.

  • Efficient in reducing fuel consumption due to better heat capture.

5. Applications

Used widely in:

  • Furnace convection sections

  • Crude oil and reformer heaters

  • Thermal oxidizers

  • Economizer tubes in boilers

  • Process gas heaters

  • Air preheaters and waste heat recovery units
