High Frequency Welding Fin Tube

ASTM A335 P22 alloy steel tube

Product Description

ASTM A335 P22 Alloy Steel Seamless Tube High Frequency Welding Fin Tube For Economizer

Product Overview

The ASTM A335 P22 High Frequency Welding (HFW) Fin Tube is manufactured by helically or longitudinally welding alloy fin strips onto a seamless P22 alloy steel base tube using high-frequency resistance welding. This finned tube is specifically designed for furnace and radiant coil applications, where high-temperature strength, pressure resistance, and thermal efficiency are crucial.

Chemical Composition

Base Tube – ASTM A335 P22

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 A335 P22

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

High Temperature Resistance: P22 material and high-chromium fin strip allow operation in up to 600–650°C.
Reliable Fin Bonding: HFW technology ensures strong metallurgical bond, minimizing thermal resistance and improving efficiency.
Oxidation and Scaling Resistance: Ideal for direct flame and high-flue gas environments.
Enhanced Heat Transfer: Fins increase surface area and promote turbulence, improving heat exchange rate inside the furnace.
Long Service Life: Resistant to thermal fatigue and corrosion, reducing maintenance frequency in demanding operations.

Applications

Power Plant Furnaces (Radiant Section)
Waste Heat Recovery Furnaces
Industrial Steam Generators
Petrochemical Process Heaters
Coal-Fired and Biomass-Fired Boilers
High-Pressure Radiator and Convection Coils
