High Frequency Welding Fin Tube

Product Description

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


Product Overview

The ASTM A335 P22 HFW Fin Tube is a high-efficiency heat transfer component, crafted by welding serrated or solid alloy fin strips onto a seamless P22 alloy steel tube using high-frequency resistance welding. It is specifically engineered for economizer coils in power plants, industrial boilers, and waste heat recovery systems, where high temperature and pressure resistance are critical.


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

  • Superior Heat Transfer: HFW process ensures close bonding between fins and tube, maximizing surface area and thermal performance.

  • Durability Under Pressure: P22 alloy steel offers high strength and creep resistance, making it suitable for high-pressure steam applications.

  • Oxidation & Corrosion Resistance: Chromium-molybdenum alloy composition provides strong resistance to oxidation, scaling, and corrosion at elevated temperatures.

  • Enhanced Lifespan: Serrated fins improve turbulence and cleaning efficiency, reducing fouling and increasing operational life.

  • Cost Efficiency: Ideal for long-term operation in power plants, reducing maintenance frequency and downtime


Applications

  • Boiler Economizers in Thermal Power Plants

  • Waste Heat Recovery Boilers (WHRB)

  • Refinery Heaters and Process Units

  • Chemical Plant Steam Generators

  • Industrial Heat Recovery Systems

  • Preheater Sections of Steam Generating Units
