Detailed Description

KL(Knurled) fin tube for Heater or Heat Exchanger Parts Base tube material: SA179 SMLS OD25.4mm x MWT 2.642mm x Length 9144mm Fin Material: AL1060; OD 57.15mm x thk 0.457mm x 8 FPI Manufacturing Process: 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. Upper Temperature limit: 250C 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 | - - - - Application: KL-type finned tube mainly used in Heater Parts, Heater or Heat Exchanger Parts Capacity: 9000 meters/day Product: 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.
