ASME SA213 T9 Alloy Steel Studded Tube , for Refineries and Boilers
The ASME SA213 T9 Alloy Steel Studded Finned Tube is a high-performance heat exchanger component widely used in industries such as petrochemicals, power plants, refineries, and boilers. This type of finned tube combines the exceptional properties of ASME SA213 T9 alloy steel with enhanced heat transfer capabilities provided by studded fins, making it ideal for applications requiring efficient heat exchange under extreme conditions.
Key Features:
1. Material Composition:
ASME SA213 T9 is a ferritic alloy steel containing chromium (Cr) and molybdenum (Mo). This composition provides excellent high-temperature strength, oxidation resistance, and corrosion resistance.
2. High-Temperature Resistance:
T9 alloy steel performs well under elevated temperatures, making it suitable for heat exchangers, superheaters, and reheaters in boiler systems.
3. Durability:
The material exhibits superior mechanical strength, long service life, and resistance to thermal fatigue.
4. Weldability:
It can be easily welded and fabricated for a variety of custom designs.
Advantages of Studded Finned Tubes:
1. Improved Heat Transfer:
The studs significantly enhance the heat exchange efficiency by increasing the tube's external surface area.
2. Fouling Resistance:
Studs help minimize fouling and scaling, especially in environments with high particulate matter, making them easier to clean and maintain.
3. Robustness:
The welded construction ensures mechanical strength and reliability even under high-pressure and high-temperature conditions.
