Solid Fin Tubes manufactured with ASTM A106 Gr. B seamless carbon steel base tubes and Carbon Steel (CS) solid fins are widely used in high-temperature heat recovery systems. Designed for durability and efficient heat transfer, this fin tube type is especially suitable for waste heat boiler applications where flue gas conditions require robust mechanical strength and stable thermal performance.

Product Overview

Solid fin tubes are produced by mechanically bonding or integrally forming carbon steel fins onto a carbon steel base tube. This structure ensures strong fin-to-tube contact, allowing efficient heat conduction and long-term stability under thermal cycling conditions.

In waste heat boilers, these tubes are typically installed in economizer sections, superheater zones, or flue gas heat recovery sections to maximize energy utilization.

Main Applications

ASTM A106 Gr. B Solid Fin Tubes are commonly used in:

Waste Heat Boilers (WHB)
HRSG (Heat Recovery Steam Generator)
Economizers in industrial boilers
Flue gas heat recovery systems
Petrochemical furnace waste heat recovery
Cement kiln exhaust heat utilization
Steel plant recovery boiler systems
Industrial high-temperature gas cooling systems
