L/LL/LK Finned Tube Fin Type: Fin Tube Tube Material: Carbon steel, stainless steel, copper, aluminum Fin Material: Copper, aluminum Fin Tube Length: No Limit Product description：L/LL/KL finned tube: Working temperature: 230℃. Features: Adopting the winding process, the production efficiency is high, the lamella distance is uniform, the heat transfer is good, the finization ratio is high, the base tube can be protected from air erosion. L/LL/KL Finned Tube Finned tube is a tube with small finned fins around its outer surface. These 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 finned 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.
