L/LL/KL Finned Tube is a tube with small finned fins around its outer surface. L/LL/KL Fin Tube fins act as a filter and a mechanism for transferring heat from the material inside the tube to or from the outer space. Finned Tubes are used in applications where heat is transferred from a hot fluid to a cooler fluid through the wall of the tube. The rate at which this heat transfer occurs depends on three factors:
The difference in temperature between the two fluids.
The coefficient of heat transfer between each fluid and the wall.
Surface area of fluid exposure
L type fin tube: Adopting the winding process, the production efficiency is high, uniform lamella distance , good heat transfer, high finization ratio, the base tube can be protected from air erosion. The aluminum fin or copper fin is folded into an L shape and continuously spirally wound on the outer surface of the base tube under the action of tension.
Usage and characteristics of Kl Type Finned Tube
KL type Finned Tube , also known as knurled finned tube, is to knuckle the base tube before winding the fins, or install a blade on the winder to knuckle the base tube, and the blade behind is used for winding the fins. Knurling and winding are carried out at the same time.

Maximum working temperature-150°C (302°F), acceptable for atmospheric corrosion resistance, poor mechanical resistance. Commonly used heat sink materials are aluminum and copper.
LL typefinned tube: Under the L-shaped foundation, the fin root completely covers the outer surface of the base tube; to some extent, this fin type guarantees better corrosion resistance. Maximum working temperature-180°C (356°F), acceptable for atmospheric corrosion resistance, poor mechanical resistance. Commonly used heat sink materials are aluminum and copper
KL type finned tube: Before the fins are continuously wound on the surface of the steel tube, the outer surface of the base tube needs to be knurled; after the fin winding is completed, the root of the fin attached to the steel tube will also be knurled to strengthen the steel tube and the fins combination. Therefore, this fin type ensures better heat transfer characteristics under L and LL fins. Maximum operating temperature -260°C (500°F), acceptable atmospheric corrosion resistance, poor mechanical resistance. Common heat sink materials are aluminum and copper
