What is the L finned tubes? How did this L process come into being and what about advantages of this type?
*Wound L finned tubes is one type of finned tubes, this type of finned tubes are widely used in industries requiring efficient heat exchange with gas/air-side media.
*Fin Structure: L-shaped fin wound and fixed on base tube (high-frequency welding or tension winding process).
*A179 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 A179 Seamless Steel Tubes
*Chemical Composition
| Carbon% | Manganese% | Phosphorus% | Sulfur% |
| 0.06-0.18 | 0.27-0.63 | 0.035max | 0.035max |
*A179 a standard for cold-drawn low-carbon steel seamless heat exchange tubes, designed specifically for heat exchange equipment such as condensers, evaporators, and heat exchangers. With its excellent thermal conductivity, formability, and economy, it is widely used in medium- and low-temperature and medium- and low-pressure heat exchange conditions.
*Mechanical Properties
| Tensile Strength, min | Yield Strength, min | Elongation in 2" or 50mm, min |
| 47ksi (325 MPa) | 26ksi (180 MPa) | 30% |
*A179 This material has excellent thermal conductivity and low metal density, which can reduce the overall load on the equipment.
*A179 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.
