Description

Alloy Steel Seamless Tube, ASME SA335 P22, HFW Fin Tube with 11-13 CR Fin Strip


Product Introduction

The ASME SA335 P22 High Frequency Welded (HFW) Fin Tube is manufactured from alloy steel seamless tubing with helically welded 11–13% chromium steel fins. This design ensures excellent heat transfer, corrosion resistance, and mechanical durability in high-temperature environments, such as furnaces, heaters, and economizers.

Chemical Composition

Base Tube – ASME SA335 P22 (Alloy Steel)

Element Content (%)
C 0.05–0.15
Mn 0.30–0.60
P ≤ 0.025
S ≤ 0.025
Si 0.50–1.00
Cr 1.90–2.60
Mo 0.87–1.13
Fe Balance

Fin Material – 11–13Cr Steel (Typical Composition)

Element Content (%)
Cr 11.0–13.0
C ≤ 0.12
Si ≤ 1.0
Mn ≤ 1.0
Fe Balance

Mechanical Properties (SA335 P22)

Property Value
Tensile Strength ≥ 415 MPa
Yield Strength ≥ 205 MPa
Elongation ≥ 30%
Hardness ≤ 192 HB
Working Temp Range Up to 600–650°C

Key Advantages

  • Excellent High-Temperature Strength
    Suitable for continuous operation under high heat and pressure.

  • Outstanding Oxidation & Sulfidation Resistance
    Chromium-rich fin material resists scaling and chemical attack in furnace atmospheres.

  • High Welding Integrity
    HFW ensures tight fin attachment with low thermal contact resistance.

  • Efficient Heat Transfer
    The extended surface area improves convective heat exchange efficiency.

  • Long Service Life
    Withstands cyclic thermal stress and harsh flue gas exposure.

Typical Applications

Used in thermal and petrochemical industries, particularly in heat exchange equipment exposed to flue gases:

  • Furnace Convection Coils

  • Boiler Economizers

  • Superheaters and Reheaters

  • Heater Tubes in Refineries & Power Plants

  • Waste Heat Recovery Units (WHRU)
