Alloy Steel High Frequency Welded Fin Tube ASTM A335 P22 11-13Cr Fin For Combustion Heater
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. Key Features and Applications:
High Thermal Efficiency: The high-frequency welding process used for the fins ensures the highest possible thermal conductivity, which significantly enhances the heat transfer rate. Durability: The use of alloy steel (ASTM A335 P22) combined with high-chromium fins increases the heat exchanger's lifespan under high temperatures and pressures. Combustion Heater Applications: Primarily used in combustion heaters where efficient heat transfer is crucial for maximizing thermal efficiency. These tubes help in the heating of water, air, or gases in systems such as industrial boilers, furnaces, and steam generators. Corrosion Resistance: The chromium in the fin material offers resistance to high-temperature oxidation and corrosion, which is critical in combustion environments where exhaust gases can be aggressive.
Typical Applications
Petrochemical Industry:
Cracking furnaces, reformers, and heat recovery systems.
Power Generation:
Heat recovery steam generators (HRSG) and boiler systems.
Refineries:
Processing units requiring high-efficiency heating.
Waste Heat Recovery:
Systems that capture and utilize heat from exhaust gases.
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.
