ASTM A106 GrB Carbon Steel HFW Welded Finned Solid Tubes for Fired Heaters
Specification ASTM A106 covers seamless carbon steel pipe for high-temperature service (Note 1) in NPS 1/8" to NPS 48"[DN 6 to DN 1200] inclusive, with nominal (aver-age) wall thickness as given in ASME B36.10M. It shall be permissible to furnish pipe having other dimensions provided such pipe complies with all other requirements of this specification. Pipe ordered under this specification shall be suitable for bending, flanging, and similar forming operations, and for welding.
Chemical Composition (%) Maximum

| A106 Gr.B | 0.30 | 0.29-1.06 | 0.035 | 0.035 | 0.10 | 0.40 | 0.40 | 0.15 | 0.40 | 0.08 |
Mechanical Properties
| Grade | Tensile Strength min | Yield Strength min | Elongation in 2" or 50mm min |
| A106 Gr.B | 60ksi (415 MPa) | 35ksi (240 MPa) | 30% |
Heat Treatment: Hot-finished pipe need not be heat treated. Cold-drawn pipe shall be heat treated after the final cold draw pass at a temperature of 1200°F (650°C) or higher.
Core Advantages of Carbon Steel HFW Welded Finned Solid Tubes in Fired Heaters
1. Superior Metallurgical Bonding Performance:
High-frequency welding (HFW) creates a strong metallurgical fusion between the fins and the base tube, eliminating gaps and preventing loosening due to thermal fatigue caused by frequent temperature rises and falls. This ensures stable heat transfer efficiency over long periods in high-temperature flue gas environments.
2. High Heat Transfer Efficiency:
Solid fin structure + dense fin arrangement significantly expands the heat exchange area.
3. Excellent High Temperature and High Pressure Resistance:
Utilizes ASTM A106 Gr.B carbon steel base pipe, long-term operating temperature can reach above 425°C. It can withstand medium to high pressure processes within the tube and possesses good mechanical strength.
4. Strong Vibration and Corrosion Resistance:
Integrated high-frequency welding ensures high fin installation strength, preventing detachment or deformation. It resists dust erosion and airflow vibration in the convection zone of the heating furnace, resulting in a longer service life than L-shaped finned tubes or embedded finned tubes.
5. Good weldability and process adaptability:
Easy to bend, U-bend, weld and assemble on-site, facilitating furnace coil layout.
6. Cost-effectiveness advantages:
Lower material and manufacturing costs compared to stainless steel or alloy finned tubes. Suitable for the less corrosive flue gas environments in most refineries, petrochemical plants and industrial furnaces.
