The ASTM A106 Gr.B Studded Fin Tube is a robust heat transfer solution designed for high-temperature and high-pressure applications. It features a seamless carbon steel base tube (ASTM A106 Grade B) with cylindrical stud fins resistance-welded perpendicularly to the tube surface. Each stud fin acts as an individual heat transfer enhancement point, creating turbulent flow to maximize thermal efficiency. Ideal for extreme conditions, this design withstands temperatures up to 450°C (842°F) and pressures exceeding 20 MPa, making it superior to traditional finned tubes in fouling-prone environments.

Chemical Composition |
Key Features |
ASTM A106 Gr.B Base Tube |
• C: ≤0.30%, Mn: 0.29–1.06%, Si: ≥0.10%, Fe: Balance. |
• Excellent oxidation resistance at high temperatures. |
Stud Fins (Typical Material: Carbon Steel) |
• C: 0.15–0.25%, Mn: 0.60–0.90%, Fe: Balance. |
• Composition matched to base tube to prevent galvanic corrosion. |
Synergy |
• Homogeneous material system eliminates bimetallic corrosion. |
• Stable in steam, oil, and non-acidic media. |

Mechanical Performance |
Key Features |
ASTM A106 Gr.B Base Tube |
• Tensile Strength: ≥415 MPa |
• High-pressure capability (ASME B31.1 compliant). |
Stud Fins |
• Shear Strength per Stud: ≥350 MPa |
• Resists mechanical/thermal shock. |
System Performance |
• Max Service Temp.: 450°C |
• Zero fin detachment under thermal cycling. |
· Power Generation: Boiler economizers, superheaters, and flue gas ducts in coal-fired plants.
· Oil Refining: Crude oil heaters, coker units, and vacuum distillation columns.
· Chemical Processing: Non-corrosive gas heaters and thermal fluid systems.
· Waste-to-Energy: Syngas coolers and incinerator heat recovery.
· Industrial Boilers: High-fouling fuel oil heaters and steam generators.
4. Why Choose Studded Fin Tubes?
· 30% Higher Fouling Resistance vs. helical fin tubes.
· Zero Galvanic Corrosion: Single-material carbon steel construction.
· ASME-Certified Safety: Complies with ASTM A106, ASME B31.1, and PED 2014/68/EU.
· Reduced Maintenance: Self-cleaning stud design minimizes scaling.
· 20+ Year Lifespan in 400°C+ environments.
