Description

HFW Fin Tube ASTM A213 T22 Alloy Steel Seamless Tube For Furnace And Heater


Product Overview

The ASTM A213 T22 HFW Fin Tube is a high-temperature alloy steel tube with high frequency welded (HFW) fins, designed for use in industrial furnaces, heaters, and boilers. The T22 alloy offers superior thermal strength, oxidation resistance, and creep resistance, making it suitable for continuous operation under extreme heat and pressure.


Chemical Composition

Base Tube – ASTM A213 T22

Element Composition (%)
Carbon (C) 0.05–0.15
Manganese (Mn) 0.30–0.60
Phosphorus (P) ≤ 0.025
Sulfur (S) ≤ 0.025
Chromium (Cr) 1.90–2.60
Molybdenum (Mo) 0.87–1.13

Fin Material – 11-13Cr Strip

Element Composition (%)
Chromium (Cr) 11.0–13.0
Carbon (C) ≤ 0.08
Manganese (Mn) ≤ 1.0
Silicon (Si) ≤ 1.0
Phosphorus (P) ≤ 0.040
Sulfur (S) ≤ 0.030

Mechanical Properties

Base Tube – ASTM A213 T22

Property Value
Tensile Strength ≥ 415 MPa
Yield Strength ≥ 205 MPa
Elongation ≥ 30%
Hardness ≤ 163 HB

Fin Material (Typical)

Property Value
Tensile Strength Approx. 450–600 MPa
Yield Strength Approx. 250–350 MPa
Hardness 150–180 HB
Heat Resistance Up to 600°C (continuous)


Advantages

  • Superior heat transfer performance for high-temperature gas environments.

  • High mechanical strength and creep resistance for prolonged service at elevated temperatures.

  • Excellent weldability and structural stability due to the seamless tube and HFW fin bonding.

  • Corrosion and oxidation resistance ensures durability in aggressive heating environments.

Applications: Convection Section of the Furnace

  • Located in the upper part of the furnace.

  • This section recovers residual heat from flue gases after combustion.

  • Flue gas temperature here is lower than in the radiant section (typically 300–700°C), making it ideal for finned tubes.

  • The fins increase surface area, enhancing heat recovery efficiency.

  • T22’s creep strength and oxidation resistance ensure reliable performance under long-term high-temperature operation.
