ASME SA192 Base Tube with Carbon Steel Fins Serrated Fin Tube for HRSG

Serrated fin tubes are widely used in Heat Recovery Steam Generators (HRSG) due to their excellent heat transfer efficiency and mechanical reliability under high-temperature operating conditions. Our serrated fin tubes are manufactured using ASME SA192 seamless carbon steel tubes as the base tube, combined with high-quality carbon steel serrated fins, ensuring optimal thermal performance and long service life.

The serrated fin design significantly increases turbulence on the gas side, breaking boundary layers and improving convective heat transfer. This makes serrated fin tubes particularly suitable for exhaust gas heat recovery systems, where efficiency, durability, and stable operation are critical.

• Base Tube Material: ASME SA192
• Fin Material: Carbon Steel
• Fin Type: Serrated (Helical)
• Manufacturing Method: High-frequency resistance welded (HFW) fins

ASME SA192 is a low-carbon steel specifically developed for high-pressure boiler and heat exchanger applications, offering excellent thermal conductivity, uniform wall thickness, and good resistance to high-temperature service environments.

• Enhanced heat transfer efficiency due to serrated fin geometry
• Strong fin-to-tube bond for reliable thermal performance
• Excellent resistance to thermal fatigue and vibration
• Suitable for high-temperature flue gas environments
• Reduced heat exchanger size and operating cost

The serrated fin structure allows for better cleaning characteristics compared to solid fins, making it ideal for HRSG systems exposed to dust-laden or corrosive exhaust gases.

• Heat Recovery Steam Generators (HRSG)
• Waste heat recovery boilers
• Power plants (combined cycle and thermal)
• Petrochemical and refinery heaters
• Industrial exhaust gas heat exchangers

• Base tube complies with ASME SA192
• Fin welding performed under strict quality procedures
• Dimensional inspection and visual examination
• Optional non-destructive testing upon request

Each serrated fin tube is produced to meet stringent industrial standards, ensuring consistent performance and reliability in critical heat transfer systems.

Our serrated fin tubes are designed to meet the demanding requirements of modern HRSG systems. By combining ASME SA192 boiler-grade tubes with carbon steel serrated fins, we deliver a product that balances thermal efficiency, mechanical strength, and cost-effectiveness.
