Alloy Steel High Frequency Welding Fin Tube ASTM A335 P22 11-13Cr Fin For Furnace

1. Material Overview

ASTM A335 P22 Alloy Steel Tube

• Specification: ASTM A335 P22 is a seamless ferritic alloy steel designed for high-temperature service.
• Composition:
  • Chromium (Cr) and Molybdenum (Mo) improve heat resistance, tensile strength, and corrosion resistance.
  • Suitable for withstanding thermal stresses in extreme conditions.
• Properties:
  • High-Temperature Strength: Maintains mechanical integrity at elevated temperatures.
  • Oxidation Resistance: Chromium enhances resistance to oxidation in furnace environments.
  • Durability: Ideal for long-term use in harsh conditions.

11-13Cr Fins

• Material: Fins made of 11-13% Chromium (stainless steel grade).
• Properties:
  • Corrosion and Oxidation Resistance: Suitable for environments with high humidity, corrosive gases, or elevated temperatures.
  • Thermal Efficiency: Ensures efficient heat transfer in furnace applications.

2. High-Frequency Welding (HFW) Finning

• Process:
  • Fins are welded onto the tube using high-frequency electric resistance welding.
  • This creates a strong metallurgical bond, ensuring the fins remain intact under extreme thermal and mechanical stress.
• Advantages:
  • Strong Bonding: Provides excellent mechanical strength for vibration-prone environments.
  • Thermal Efficiency: Ensures consistent heat transfer without gaps or weak points.
  • Durability: Resistant to thermal cycling and mechanical wear.

3. Application in Furnaces

• Role:
  • In furnace systems, finned tubes are used to enhance heat transfer, ensuring efficient heating of fluids or gases.
  • Typical applications include reheat furnaces, petrochemical cracking furnaces, and waste heat recovery systems.
• Why P22 with 11-13Cr Fins:
  • Heat Resistance: The combination of P22 alloy steel and chromium-rich fins provides exceptional performance at high temperatures.
  • Oxidation Protection: Resistant to scaling and oxidation, even in direct flame exposure or high-temperature flue gases.
  • Energy Efficiency: Enhanced heat transfer reduces fuel consumption and improves furnace efficiency.

4. Key Advantages

1. High-Temperature Performance:
   • ASTM A335 P22 material withstands temperatures up to 600°C or more, making it ideal for furnaces.
2. Corrosion and Oxidation Resistance:
   • 11-13Cr fins protect the tube from corrosive gases and oxidation, extending service life.
3. Enhanced Heat Transfer:
   • High-frequency welded fins improve heat exchange efficiency, reducing energy costs.
4. Durability:
   • The strong bond between fins and tubes ensures reliability in demanding environments with thermal cycling and vibrations.
5. Versatility:
   • Suitable for various furnace configurations and applications in multiple industries.

Typical Applications

1. Petrochemical Industry:
   • Cracking furnaces, reformers, and heat recovery systems.
2. Power Generation:
   • Heat recovery steam generators (HRSG) and boiler systems.
3. Refineries:
   • Processing units requiring high-efficiency heating.
4. Waste Heat Recovery:
   • Systems that capture and utilize heat from exhaust gases.
5. Industrial Furnaces:
   • Reheat and annealing furnaces in steel production and other heavy industries.

Why Choose HFW Fin Tubes with P22 and 11-13Cr Fins?

• High Efficiency: Ensures optimal heat transfer for energy savings.
• Longevity: Resistant to high-temperature corrosion and oxidation, minimizing maintenance costs.
• Reliability: Robust construction suitable for harsh industrial conditions.
• Cost-Effective: Reduces downtime and energy costs over the long term.
