High-Frequency Welded Serrated Finned Tubes Base Tube: T22 Alloy Steel | Fins: Carbon Steel (CS)

T22-CS Synergy: Advanced Heat Transfer Solution

Our high-frequency welded serrated finned tubes combine T22 alloy steel base tubes with carbon steel (CS) fins for

unmatched thermal efficiency in extreme environments. The T22 base tube delivers superior high-temperature strength

(up to 550°C), while CS fins maximize heat dissipation through serrated edges that disrupt boundary layers. Ideal for

boilers, HRSGs, and waste-heat recovery systems.

Precision Chemistry: T22 & CS Composition

Optimized for Corrosion Resistance and Thermal Conductivity

Notes: T22 resists oxidation in steam environments; CS fins enhance thermal conductivity (45–50 W/m·K).

T22-CS Dimensional Tolerances: Engineered Accuracy

Guaranteed Fit for Critical Applications

T22-CS Application Domains

1. Power Generation: Boiler economizers (coal/gas-fired plants), air preheaters.

1. Petrochemical: Waste-heat recovery in reformers & crackers (operating temp: 400–550°C).

1. Marine: Exhaust gas boilers for LNG carriers.

1. Industrial HVAC: High-efficiency heat exchangers in chemical processing.
