ASME SA192 Carbon Steel Fin Tube Serrated With CS Fin Strip For Economizer And Heat Recovery
This high-efficiency heat exchange component is specifically engineered for boiler economizers and industrial waste heat recovery systems. It utilizes ASME SA192 carbon steel as the base tube material, the carbon steel fin strip is helically wound and securely welded onto the outer surface of the base tube through high-frequency welding process, forming distinctive serrated fin geometry.
This unique design effectively disrupts fluid boundary layers, enhances turbulence, and significantly improves heat transfer efficiency (20%-30% higher than smooth fins). The product is particularly suitable for harsh operating conditions including high-temperature/pressure environments and dusty flue gas applications in coal-fired boilers, heat recovery steam generators (HRSG), and petrochemical plants, ensuring both energy efficiency improvement and long-term operational reliability.

Mechanical Properties
| Component | Mechanical Performance | Key Features |
| ASME SA192 Base Tube | · Tensile Strength: 415 - 535 MPa · Yield Strength: ≥ 240 MPa · Elongation: ≥ 30% · Hardness: 160-190 HB | · Excellent cold bending and welding properties, fabrication in complex piping systems. · Long-term service temperature up to 400°C with strong creep resistance. · More economical than alloy steel tubes while meeting pressure requirements for standard boilers and heat exchangers. |
| CS Fin Strip | · Tensile Strength: 350 - 500 MPa · Yield Strength: ≥ 200 MPa | · HFW metallurgical bond. High strength, vibration-resistant, no peeling. · High hardness resists flue gas abrasion. Significantly extends service life in harsh conditions. · Matched thermal expansion with base tube. Expands/contracts as one, prevents thermal stress. · Ideal strength-toughness balance. Resists flow-induced fatigue for safe, stable operation. |
