ASTM A213 T9 Alloy Steel Studded Fin Tube With Alloy/Stainless Steel Studs for Boiler or Heater

This studded fin tube is constructed from ASTM A213 T9 alloy steel base tube, featuring welded alloy steel or stainless steel studs (pins) to enhance heat transfer efficiency in high-temperature and high-pressure environments. Designed for boilers, heaters, and heat exchangers, the studded surface significantly increases the heat-absorbing area, improving thermal performance while resisting ash deposition and corrosion.

Mechanical Properties

2. Key Features

(1) High Durability in Harsh Conditions

Resists high-temperature corrosion, oxidation, and ash fouling, ideal for boilers, heaters, and flue gas applications

(2) Patented stud welding technology + T9 Cr-Mo base tube = 3x longer service life at 650°C vs conventional tubes

(3) Alloy steel or stainless steel (304/316) studs are welded to the tube surface to significantly increase heat transfer area and efficiency

(4) Provides high heat transfer in a relatively compact space, making it ideal for applications with space constraints

(5) Corrosion resistance, wear resistance, low contact thermal resistance, high stability

3. Key Applications

• Power plant boilers
• Petrochemical heaters
• Waste heat recovery systems
• Marine & offshore heat exchangers
• Power Plants
