Product Overview

This High Frequency Welded (HFW) fin tube is constructed with a seamless alloy steel base tube (ASTM A335 P22) and 11-13% chromium fin strips, designed for high-temperature heat exchange in furnace convection coils, superheaters, and heaters. The Cr-based fins offer enhanced oxidation resistance, making the product ideal for harsh combustion gas environments.

Chemical Composition

Base Tube - ASTM A335 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 for high-temp fins)

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

Mechanical Properties (ASTM A335 P22)

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

Advantages

High Heat Resistance
Base material (P22) and Cr fins maintain structural integrity under sustained high temperatures.
Corrosion & Oxidation Resistance
11-13Cr fin strips protect against flue gas corrosion, sulfur compounds, and high-temp oxidation.
Durable Weld Bonding
HFW process ensures strong mechanical connection between tube and fins, with low thermal resistance.
Long Service Life
Ideal for severe service in petrochemical and power generation industries.

Applications

Used primarily in the convection section of furnaces and heaters, especially in oil refineries, chemical plants, and power boilers.

Application Zones:

Convection Coil Tubes
Positioned after radiant tubes to absorb lower-temperature flue gas energy.
Steam Superheaters
Heat Recovery Systems (HRSG, WHRU)
