ASTM A179 Carbon Steel Wound L Type Finned Tube With Aluminum Fins For Oil Fire Furnace
ASTM A179 Carbon Steel L Type Fin Tube is a fin tube made of aluminum fin strip wounded into an L-shaped spiral under tension and wrapped tightly around the outer surface of the base tube. The tension in fin strips of the L Type Fin Tube wraps around the tube, causing the fin feet to press forcefully against the base tube, holding the fins firmly in place. L Type Fin Tube is usually used in air coolers in petrochemical, power generation, paper and pulp, building heating and other industries, and heat exchangers in power plants, like electricity, nuclear, thermal and geothermal power plants.
The key purpose of L-Type Fin Tubes is to enhance heat transfer efficiency. The L-shaped fins increase the surface area of the base tube, which improves heat dissipation or heat absorption in applications requiring high heat transfer rates.
