ASTM A179, ASME SA179, Carbon Steel Seamless Tube, Low Fin Tube, Heat Exchanger Tube
ASTM A179 / ASME SA179 Low Fin Tube is a carbon steel seamless tube with integral low fins formed on the external surface. These fins increase the outer surface area of the tube, improving heat transfer efficiency in heat exchangers while maintaining compact designs.
Element | Composition (%) |
---|---|
Carbon (C) | ≤ 0.06 |
Manganese (Mn) | 0.27 – 0.63 |
Phosphorus (P) | ≤ 0.035 |
Sulfur (S) | ≤ 0.035 |
Property | Value |
---|---|
Tensile Strength | ≥ 325 MPa (47 ksi) |
Yield Strength | ≥ 180 MPa (26 ksi) |
Elongation (L=50mm) | ≥ 35% |
Hardness | Typically ≤ 77 HRB |
Enhanced heat transfer due to increased outer surface area.
Compact design reduces heat exchanger size and weight.
Strong fin bond (integral fins) prevents fin detachment.
Good performance under low to moderate pressure and temperature.
Cost-effective for air and water-side applications.
