Serrated Finned Tube for HRSG (Heat Recovery Steam Generator) is a high-efficiency heat transfer component designed to improve thermal performance in waste heat recovery systems. This type of fin tube uses a continuous serrated fin structure welded or mechanically bonded onto the base tube, increasing the effective heat transfer surface area while maintaining strong gas-side turbulence.
The base tube material, ASME SA210 Gr. C, is a carbon steel boiler and superheater tube material widely used in high-temperature pressure applications. It provides suitable mechanical strength, thermal conductivity, and resistance to operating conditions commonly found in HRSG economizer, evaporator, and superheater sections.
Serrated fin design helps reduce boundary layer formation on the gas side, improving heat transfer efficiency compared with plain tubes while reducing overall equipment size. It is commonly applied in combined cycle power plants, industrial waste heat recovery units, and energy conversion systems where compact and reliable heat exchange performance is required.
ASME SA210 Gr. C serrated finned tubes are commonly used in:
| Item | Typical Range |
|---|---|
| Base Tube Material | ASME SA210 Gr. C Carbon Steel |
| Tube Outside Diameter | 25.4 mm – 76.2 mm |
| Tube Wall Thickness | 2.5 mm – 8.0 mm |
| Tube Length | Up to 18,000 mm |
| Fin Height | 10 mm – 25 mm |
| Fin Thickness | 0.8 mm – 2.5 mm |
| Fin Density | 4 – 12 fins/inch |
| Fin Type | Serrated / Segmented Spiral Fin |
| Fin Material | Carbon Steel, Alloy Steel, Stainless Steel (as required) |
| Manufacturing Standard | ASME, ASTM, customer specification |
Dimensions can be customized according to HRSG engineering requirements.
| Element | Chemical Requirement (%) |
|---|---|
| Carbon (C) | 0.35 max |
| Manganese (Mn) | 0.29 – 1.06 |
| Phosphorus (P) | 0.035 max |
| Sulfur (S) | 0.035 max |
| Silicon (Si) | 0.10 min |
