L/LL/KL finned tubes enhance heat transfer efficiency through innovative design and material applications. These finned tubes meet various temperature and corrosion resistance requirements, providing optimal solutions for multiple industries.
1. L Type Finned Tube
The fin strip of the L finned tube is L-shaped and tightly wound around the outer surface of the pipe. The L-shaped design offers enhanced corrosion protection. It is an economical choice for low-temperature applications, supporting temperatures up to 150°C.
Fin Materials: Aluminum and Copper
Base Tube Materials: Not limited
Advantages: Suitable for low-temperature applications; cost-effective; allows easy removal and reuse of failed fins; compatible with thin-walled tubes without spiral grooves; corrosion resistance up to 130°C.
2. LL Type Finned Tube
Similar to the L type tube, the LL variant features overlapping fin feet, providing better corrosion protection. These tubes operate at temperatures up to 180°C and offer higher durability in corrosive environments.
Fin Materials: Aluminum and Copper
Base Tube Materials: Not limited
Advantages: A cost-effective alternative to extruded fins in corrosive environments; maximum operating temperature of 170°C.
3. KL Type Finned Tube (Knurled Aluminum Tube)
The KL finned tube is manufactured similarly to the L type tube but features a knurled surface on the base tube. This knurling enhances the bond between the pipe and the fin, significantly improving heat transfer performance. These tubes can withstand temperatures up to 260°C, making them ideal for medium-temperature applications.
Fin Materials: Aluminum and Copper
Base Tube Materials: Not limited
Advantages: Provides resistance to corrosion and vibration; capable of withstanding temperatures up to 320°C; delivers high thermal performance and protection against air corrosion.
