ASTM A106 GR.B HFW U-FIN TUBE FOR HEAT EXCHANGER
ASTM A106 GR.B HFW U-FIN tube is a type of heat exchanger tube made from ASTM A106 Grade B carbon steel. It is manufactured using the High Frequency Welding (HFW) process, which utilizes high-frequency current to create a strong, durable weld.
The U-FIN design refers to the U-shaped fins on the outer surface of the tube. These fins significantly increase the heat transfer surface area, enhancing thermal efficiency between the internal fluid and the external environment.
This tube is ideal for heat exchanger applications requiring high thermal performance, especially in power generation, petrochemical, and HVAC systems.
