ASTM A213 T9 Alloy Steel Studded Fin Tube for Furnace

ASTM A213 T9 Alloy Steel Fin Tube, Studded Fin Tube for Furnace

Product Overview

ASTM A213 T9 Studded Fin Tube is a high-performance heat transfer component widely used in furnace and heater applications, particularly in convection zones. The tube body is made from T9 alloy steel, and carbon steel or alloy steel studs are resistance welded onto the tube’s surface in a uniform pattern. This design significantly enhances the heat transfer area and improves thermal efficiency in high-temperature and corrosive environments.

Chemical Composition – ASTM A213 T9 (Base Tube)

Mechanical Properties – ASTM A213 T9

Stud Information

• Material: Carbon Steel / Alloy Steel

• Attachment: Resistance welding

• Spacing: Typically 10–15 mm apart in helical or parallel arrangement

Advantages

• Maximized Heat Transfer Area
  The studs increase the outer surface area significantly, improving convective heat transfer efficiency, especially in gas-to-liquid or gas-to-gas applications.

• High Temperature & Pressure Resistance
  T9 alloy steel is specially formulated to endure high-temperature environments, making it suitable for furnace conditions up to 650°C.

• Strong Weld Bonding
  Studs are welded using resistance welding, ensuring strong adhesion and long service life under thermal cycling.

• Ideal for Harsh Conditions
  With excellent oxidation resistance and creep strength, studded fin tubes are ideal in sooty, dusty, or corrosive environments.

• Easy Maintenance
  The wide stud spacing makes it easier for soot blowers or manual cleaning, ensuring consistent heat transfer performance.
