What is the L finned tubes?
*Wound L finned tubes this type of finned tubes are widely used in industries requiring efficient heat exchange with gas/air-side media. L-shaped fin wound and fixed on base tube (high-frequency welding or tension winding process).
*ASME SA179 CS L type finned tubes + AL1060 fins this is a high-efficiency heat transfer component specifically designed for boiler economizers, offering excellent heat recovery, cost-effectiveness, and reliability in flue gas waste heat recovery scenarios.Besides, SA179 carbon steel wound L-finned tubes combine the excellent thermal conductivity and low cost of ASTM A179 seamless carbon steel base tubes with the enhanced heat transfer performance of L-shaped fins, making them an ideal choice for gas-liquid heat exchange scenarios with medium to low temperature and pressure requirements.
Core Characteristics of SA179 Seamless Steel Tubes
*Chemical Composition
| Carbon% | Manganese% | Phosphorus% | Sulfur% |
| 0.06-0.18 | 0.27-0.63 | 0.035max | 0.035max |
*SA179 is a standard for cold-drawn low-carbon steel seamless heat exchange tubes, designed specifically for heat exchange equipment such as economizers, condensers, evaporators, and heat exchangers. It is widely used in medium- and low-temperature and medium- and low-pressure heat exchange conditions, due to its excellent thermal conductivity, formability, and economy.
*Mechanical Properties
| Tensile Strength, min | Yield Strength, min | Elongation in 2" or 50mm, min |
| 47ksi (325 MPa) | 26ksi (180 MPa) | 30% |
*SA179 This material has excellent thermal conductivity and low metal density. SA179 It has excellent formability, and the cold drawing process ensures high dimensional accuracy of the tubes; it also has good weldability and plasticity, allowing for a tight fit when expanded with the tube sheet, reducing the risk of crevice corrosion and meeting the sealing requirements between the heat exchange tubes and the tube sheet.
