wrapped fin

KL Fin (or Knurled L fin): with metal strip wounded on the core tube with knurled suface The fin is wrapped around the tube and the foot is rolled into the outer surfaceof the pre knurled tube and secured at each end. Gives good surface protectionto the tube and improved heat transfer compared to the L or LL type fin. Usedfor moderate temperature cool applications.

LL-type finned tube makes the trapezoidal cross-section forming by rolling combine closely with the heat flux density distribution size. The fins combine tightly with the tube,which makes the thermal efficiency higher and put an end to thermal resistance that brings by the non eliminate contact from segment gap of the string type finned tube. 1 Features: The winding technology improves production efficiency and heat transfer, makes the average fin pitch and higher proportion between fins and tube. At the same time, the base tube can be protected from air erosion. 2 Application: LL-type finned tube mainly used in petrochemical, electric power, paper making, tobacco, building heating and other industry such as air cooler, air heater and air heater of food industry, plant starch spray drying system. The fin is wrapped around the tube with an overlapping foot and secured at each end. Gives good surface protection to the tube. Used for moderate temperature coolingapplications. Material: Copper, Carbon Steel, Copper Stainless Steel, Alloy, Aluminium Bare tube OD: 15.88-45mm Fin Pitch: 2.1-5.0mm Fin Height: <16mm

L Fin (or wrapped fin) The fin is wrapped around the tube and secured at each end. Gives some surface protection to thetube. Used for moderate temperature cooling applications. Material: Carbon Steel, Copper Stainless Steel, Alloy, Aluminium Bare tube OD: 16-63mm Fin Pitch: 2.1-5.0mm Fin Height: <17mm Fin Thick: About 0.4mm Capacity: 2000 meters
