Serrated Fin Tube High Frequency Welding Tube ASTM A213 T11 For Furnace And Heater

Serrated Fin Tube, High Frequency Welding Tube, ASTM A213 T11, For Furnace and Heater

Overview

The Serrated Fin Tube made from ASTM A213 T11 alloy steel and fabricated via High Frequency Welding (HFW) is specifically engineered for high-temperature applications such as furnaces and industrial heaters. The serrated fin structure maximizes turbulence and heat transfer efficiency, making it a superior choice for heat recovery and fuel efficiency in power plants, petrochemical refineries, and thermal processing units.
