ASME SA106 GRADE B Carbon Steel Fin Tube HFW Type for Fired Heater
Yuhong Holding Group Co., Ltd is a leading manufacturer and supplier of industrial equipment, specializing in high-quality heat exchangers, fired heaters, air coolers, and associated components. With an annual production capacity exceeding 6000 tons, we are committed to providing reliable and efficient solutions for a wide range of industries. One of our standout products is the ASME SA106 GRADE B Carbon Steel Fin Tube (HFW Type), designed specifically for optimal performance in fired heaters.
ASME SA106 GRADE B is a widely used material for high-temperature and high-pressure applications due to its excellent mechanical properties and chemical composition. The high-frequency welded (HFW) fin tube made from this material offers superior heat transfer efficiency and durability in fired heaters.

| Tensile Strength | ≥ 415 MPa (60,000 psi) |
| Yield Strength | ≥ 240 MPa (35,000 psi) |
| Elongation | ≥ 30% |
High-frequency welded (HFW) fin tubes are widely used in fired heaters due to their exceptional heat transfer capabilities and reliability under high-temperature conditions. Typical parameters for fin tubes in fired heaters include:
| Parameter | Specification |
|---|---|
| Base Tube Material | ASME SA106 GRADE B Carbon Steel |
| Fin Material | Carbon Steel, Stainless Steel |
| Fin Height | 10–15 mm |
| Fin Thickness | 0.8–1.5 mm |
| Fin Pitch | 8–12 fins per inch |
| Operating Temperature | Up to 400°C |
| Manufacturing Type | High-Frequency Welding (HFW) |
These tubes are designed to maximize heat transfer efficiency while ensuring durability and resistance to thermal fatigue in harsh operating conditions.
| Application | Function |
|---|---|
| Heat Transfer Enhancement | Increases surface area for improved heat exchange between flue gases and process fluid, boosting thermal efficiency. |
| Energy Efficiency | Reduces fuel consumption by maximizing heat recovery from combustion gases, lowering operational costs. |
| Compact Design | Allows for compact heater construction due to high heat transfer density, saving space in industrial plants. |
| High-Temperature Operations | Withstands extreme temperatures in fired heaters (e.g., refinery/petrochemical heaters) while maintaining structural integrity. |
| Corrosion Resistance | Protects against corrosive flue gases and combustion byproducts when made with materials like stainless steel or alloy coatings. |
| Reduced Fouling | Finned geometry minimizes ash or particulate buildup, ensuring sustained performance in dirty gas environments. |
| Uniform Heat Distribution | Ensures even heat distribution across the tube bundle, preventing hot spots and prolonging equipment lifespan. |
| Process Flexibility | Adaptable to diverse fuels (gas, oil, etc.) and process conditions due to customizable fin density, height, and tube materials. |
| Emission Control | Enhances combustion efficiency, reducing unburned hydrocarbons and emissions (e.g., CO, NOx) for compliance with environmental regulations. |
HFW Finned Tubes: Manufactured via high-frequency welding, ensuring strong bonding between fins and base tubes for durability under thermal stress.
Typical Use Cases: Fired heaters in refineries, petrochemical plants, power generation, and industrial boilers.
Materials: Often stainless steel, carbon steel, or alloys (e.g., Incoloy) for high-temperature/corrosive environments.
