L(Wrapped) fin tube:
Base tube material: SA213 TP304 SIZE:OD19.05mm * 1.25mm THK * 3633mm LG
Fin Material: AL1060; OD38.1mm X 275.6FPIX 0.4 mm THK
Manufacturing Process:
The fin is wrapped around the tube and secured at each end. Gives some surface protection to thetube. Used for moderate temperature cooling applications.
Upper temperature limit: 120°C
Reference :
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
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.
