ASTM A213 T9 Studded Fin Tubes for Fired Heaters are high-performance heat transfer components designed for demanding high-temperature service environments, especially in refinery furnaces, petrochemical heaters, and industrial fired heater applications.
The tube base material is manufactured according to ASTM A213 T9, a chromium-molybdenum alloy steel containing approximately 9% chromium and 1% molybdenum. This alloy provides excellent resistance to high-temperature oxidation, creep deformation, and thermal fatigue, making it suitable for radiant and convection sections of fired heaters operating under severe thermal conditions.
Studded fin tubes improve heat transfer efficiency by increasing the external surface area of the tube. Compared with plain tubes, the welded studs create enhanced turbulence around the tube surface, improving heat absorption and furnace efficiency while maintaining reliable mechanical performance during long-term operation.
Our ASTM A213 T9 studded fin tubes are manufactured with strict control of welding quality, dimensional accuracy, and material performance to meet the requirements of critical industries such as refining, chemical processing, and power generation.
ASTM A213 T9 studded fin tubes are widely used in high-temperature heating equipment, including:
ASTM A213 T9 is a ferritic alloy steel containing chromium and molybdenum elements. The material provides:
The studded fin structure increases the external heat transfer area and improves gas-side heat exchange efficiency.
Compared with conventional plain tubes, studded tubes provide:
The studs are welded directly onto the tube surface, ensuring:
The dimensions of ASTM A213 T9 studded fin tubes can be customized according to customer requirements and fired heater design conditions.
