Lord Fin Tube-A213 TP304 Laser welding finned tube
ASTM A213 TP304 Laser-Welded Finned Tubes
ASTM A213 TP304 laser-welded finned tubes represent the pinnacle of heat transfer technology, combining premium austenitic stainless steel with precision laser welding to deliver exceptional performance in demanding thermal applications.
ASTM A213 TP304 Material Properties
ASTM A213 TP304 is a standard specification for seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes. The TP304 grade specifically refers to a versatile austenitic chromium-nickel stainless steel with excellent corrosion resistance and formability.
Laser Welding Technology in Finned Tube Manufacturing
Laser welding technology revolutionizes finned tube production by creating a metallurgical bond between the base tube and fins through precise, high-energy laser beams. This process offers significant advantages over traditional welding methods:
Minimal Heat-Affected Zone
Laser welding creates an extremely narrow heat-affected zone (HAZ), preserving material properties and reducing thermal distortion.
Superior Bond Strength
The laser creates a deep, narrow weld with excellent penetration, resulting in joint strength often exceeding the base materials.
Precision and Consistency
Computer-controlled laser systems ensure consistent weld quality along the entire tube length, eliminating human error.
