ASME SA192 HFW Serrated Fin Tube Convection Carbon Steel Seamless Tube For Furnace
Carbon Steel Seamless Tube ASME SA192 HFW Serrated Fin Tube Convection Tube For Furnace
Description:
This product is a High Frequency Welded (HFW) Serrated Fin Tube, manufactured from ASME SA192 carbon steel seamless tube as the base. Serrated carbon steel fins are welded along the tube’s outer surface to improve heat transfer performance in convection sections of industrial furnaces.
Chemical Composition (ASME SA192):
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.18 |
| Manganese (Mn) | 0.27 – 0.63 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
Mechanical Properties (SA192):
| Property | Value |
|---|---|
| Tensile Strength | ≥ 325 MPa (47 ksi) |
| Yield Strength | ≥ 180 MPa (26 ksi) |
| Elongation | ≥ 35% |
| Hardness (optional) | ≤ 79 HRB |
Advantages:
-
Cost-Effective: Carbon steel offers a balance of strength and affordability.
-
Efficient Heat Transfer: Serrated fins increase surface area and induce turbulence.
-
Strong Bonding: High-frequency welding ensures durable fin-to-tube connection.
-
Good for High Pressure: SA192 is designed for high-pressure applications, ideal for boilers and furnaces.
-
Easy Fabrication: Suitable for bending and coiling after fin welding.
Application in Furnace (Convection Section):
-
Placed above the radiant section of a furnace, where flue gas temperatures are lower but still high.
-
Used to recover waste heat and preheat feedwater, air, or process fluids.
-
Common in petrochemical plants, refineries, steam boilers, and power stations.
-
Functions as the convection tube bank to increase overall thermal efficiency.
