ASTM A179 Carbon Steel Embedded G Fin Tube for Waste To Energy Boilers
ASTM A179 cold-drawn low-carbon seamless tube is the most popular and cost-effective base tube choice for embedded G finned tubes (especially steel-aluminum embedded G finned tubes, most widely used; cost-effective).
ASTM A179 specification covers minimum-wall-thickness tubular heat exchangers, condensers, and similar heat transfer apparatus. Its core advantages lie in four key aspects: processing adaptation, heat transfer, structure, and cost.
Chemical Composition (%) Maximum
| Grade | C | Mn | P | S |
| A179 | 0.06-0.18 | 0.27-0.63 | 0.035 | 0.035 |
Mechanical Properties
| Grade | Tensile Strength min | Yield Strength min | Elongation in 2" or 50mm min |
| A179 | 47ksi (325 MPa) | 26ksi (180 MPa) | 35% |
Main Applications
Boiler Economizers / Superheaters / Reheaters
Auxiliary Heat Exchangers
Petrochemical & Refinery:Air Coolers,Waste Heat Recovery
HVAC & Refrigeration:Evaporators/condensers for large commercial HVAC
Key Advantages of A179 Carbon Steel Embedded G fin Tubes for These Applications
High Mechanical Strength: ASTM A179 seamless tubes can withstands high pressure, vibration, and thermal cycling (critical for boilers and air coolers).
More Importante Is Cost-Effective: Cheaper than stainless steel alloys for moderate corrosion environments!
Compact Design: Fin tubes with high heat transfer density reduces equipment size and footprint.
Reliable Bonding: A179 Fin tubes with mechanical interlocking eliminates contact resistance, stable at 450°C more.
