L/LL/KL Finned Tube

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.

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 pipe, the outer surface of the base pipe needs to undergo a knurling process; after the fins are wound, the root of the fin attached to the steel pipe will also be knurled to strengthen the steel pipe and Combination of fins. For this reason, this fin type ensures better heat transfer characteristics under the fins of L and LL. Maximum working temperature-260°C (500°F), acceptable for atmospheric corrosion resistance, poor mechanical resistance. Commonly used heat sink materials are aluminum and copper

L/LL/KL Finned Tube applications

Application: Mainly used in air coolers in petrochemical, electric power, paper making, tobacco, building heating and other industries, air heaters and air heaters in spray drying systems such as vegetable protein and starch in the food industry. Blast furnace and converter systems, power generation: condensate exhaust gas discharged from steam turbines, condensate contact cycle cooling condensation, fossil and nuclear power plants, air conditioners (Freon, ammonia, propane), waste incineration equipment, compressor coolers, etc.

We customized finned tube according to customer indivisual requirement, for more details about L/LL/KL finned tube please inquire us!
