L/LL/KL Finned Tube

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 KL Fin Tube 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 KL fin tube 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/KLM/ Finned Tube 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.
