    Bare Tube OD: 16mm-63mm Fin Pitch: 2.1mm-5mm

    LL Fin (or Overlapped) fin tube

    Base tube material: SA179 SMLS OD31.8mm * 2.7mm THK * 4000mm LG
    Fin Material: AL1060; OD57.2mm X 10FPIX 0.4 mm THK

     

    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.
     


    Manufacturing Process:
    The fin is wrapped around the tube with an overlapping foot and secured at each end,
    making 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.and gives good surface protection to the tube. Used for moderate temperature coolingapplications.
    Working temperature: 230 ℃

    Material: Copper, Carbon Steel, Copper Stainless Steel, Alloy, Aluminium
    Bare tube OD: 16-63mm Fin Pitch: 2.1-5.0mm Fin Height: <17mm

     

    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.
