Welding fin tubes, specifically the helical serrated type with a base tube made of ASTM A335 Grade P9, are advanced heat transfer components designed for high-efficiency applications in demanding environments. This configuration combines the mechanical strength and heat resistance of the base tube with the enhanced heat transfer properties provided by the serrated fins.
ASTM A335 Grade P9: This chromium-molybdenum alloy steel offers excellent high-temperature strength, corrosion resistance, and oxidation resistance, making it ideal for high-pressure and high-temperature environments.
