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, with carbon steel fin strips helically wound and securely welded onto the outer surface 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 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 for 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

Elongation: ≥ 25%

Hardness: 160-210 HB

High tensile strength maintains structural rigidity after forming, resistant to deformation or breakage under long-term use.

Serrated fin shape disrupts fluid flow and maximizes heat transfer efficiency.

Ensures strong metallurgical bonding with carbon/alloy steel base tubes via HFW.

Wide operating temperature range (-20°C~400°C), with optional galvanizing/aluminizing for corrosive environments.

Key Features

Simple and economical installation: Maximum length of 6 meters reduces connection points, making installation more economical and fast while reducing joint leakage probability.
Low maintenance: Requires no maintenance after installation.
High efficiency: Heat dissipation area is more than 8 times of smooth tube with minimal internal flow resistance.
Long service life: High mechanical strength (tensile strength >200MPa) with hot-dip galvanized protection inside and outside.

Key Applications

Power Industry

Power plant boiler economizers
Heat Recovery Steam Generators (HRSG) for gas turbines
Air preheaters

Petrochemical Industry

Waste heat recovery in catalytic cracking units
Convection sections of petrochemical heaters
Natural gas processing equipment

Industrial Waste Heat Recovery

Sintering machine waste heat recovery in steel plants
