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: 250°C
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.
