ASTM A106 Gr.B Carbon Steel HFW Solid Finnd Tube For Boiler and Heat Exchanger
An ASTM A106 GrB Carbon Steel HFW Soid Find Tube refers to a high-performance finned tube made from ASTM A106 Grade B carbon steel, designed for enhanced heat transfer in boiler and heat exchanger applications. The tube is manufactured using High-Freguency Welding technology, ensuring a strong, leak-proof bond between the base tube and the soid fins. The solid fins increase the surface area. improving thermal efficiency in high-temperature and high-presure environments.
