ASTM A213 T11 Alloy Steel Seamless Tube HFW Serrated Fin Tube for Oil & Refinery


Brief Introduction

This finned tube combines ASTM A213 T11 alloy steel as the base tube and is enhanced with serrated fin strips through High Frequency Welding (HFW). It is specifically engineered for high-temperature and high-pressure heat transfer systems such as refineries and petrochemical plants.


Base Tube: ASTM A213 T11 (Low Alloy Steel)

Chemical Composition (T11)
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
Mechanical Properties (T11)
Property Value
Tensile Strength ≥ 415 MPa
Yield Strength ≥ 205 MPa
Elongation ≥ 30%
Hardness ≤ 85 HRB


Advantages

  • Excellent oxidation and corrosion resistance under high temperature.

  • Serrated fins increase turbulence, enhancing heat transfer by 30–50% over plain fins.

  • HFW bonding ensures strong adhesion and long service life under vibration.

  • Withstands thermal cycling in refinery applications.

  • Customizable tube-fin combinations for optimized performance.


Applications

Used in oil refineries and petrochemical plants in:

  • Furnace convection sections

  • Air preheaters

  • Process gas coolers

  • Heat recovery units

  • Economizers
