L / ll / KL Finned Tube is a kind of tube with small fins on the outer surface. L / ll / KL finned tube fins are used as filters and mechanisms to transfer the heat of the materials in the tube to or from outer space. Finned Tubes are used to transfer heat from hot fluids to colder fluids through the tube wall. The rate at which this heat transfer occurs depends on three factors:
The temperature difference between the two fluids.
The heat transfer coefficient between each fluid and the wall.
Surface area of liquid exposure.
L-shaped finned tube: winding process is adopted, with high production efficiency, uniform fin spacing, good heat transfer and high refinement rate. The basic tube can prevent air corrosion. 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.
The maximum operating temperature is - 150 ° C (302 ° f), the atmospheric corrosion resistance is acceptable, and the mechanical resistance is poor. The commonly used radiator materials are aluminum and copper.
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.
