Solid OD31.8 Mm L/LL/KL Type Fin Tube , Overlapped LL Foot Soldered Fin Tu

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 Reference Drawing : 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. - - - - Name Base tube (OD) mm Fin Pitch (mm) length (m) Min Max Min Max Min Max Extruded aluminum fin tube 8 51 1.6 10 0.5 20 L/LL/KL aluminum fin tube 16 63 2.1 5 0.5 15 Embedded aluminum fin tube 16 63 2.1 5 0.5 15 Low fin tube 10 38 0.6 2 0.5 20 Spiral fin tube 12.7 70 0.5 20 ERW HF spiral fin tube 16 219 3 25 0.5 28 ERW HF spiral serrated fin tube 16 219 3 25 0.5 28 Serrated width(mm) 10 min~26 max Serrated depth(mm) 4 min~16 max ERW studded tube 25 219 8 30 2 15 DC ERW H/HH fin tube 25 63 8 30 1 15 H/HH fins Length(mm) 60 min-150 max Thickness(mm) 1.5 min~4 max Width(mm) 30 min~50 max - - - - Capacity: 9000 meters/day Products&Inspection Deatails: TPI REPORT BY BV Following documentations should be reviewed & endorsed: Incoming inspection report for raw material including bare tube/alu.tube / alu. strip / steel strip Mill test cetification for bare tube Mill test cetification for fin (alu.tube / alu. strip / steel strip) Mill test cetification for finned tube Finned tubes dimension & visual inspection reports Packaging: sea worthy with plastic cap for each edge of core tube , finned tubes shall be put on the metal frame with wooden walls and plastic layer be considered between tubes rows to avoid damage and deformation of the fins Manufacturing FAQ About our company A------We have three company, 1.
