Longitudinal Finned Tubes are produced by resistance welding fins in diametrically opposite pairs. The way channels are welded on the external surface of the tube makes them highly efficient.
Longitudinal Finned Tubes are formed from a U channel of material, with the base being pressure rolled and spot welded to the tube or pipe. The number of fins must always be a multiple of four.
Longitudinal Finned Tube material specifications:
Materials of tubes: Carbon Steel (A106/A179/A192/A210) Stainless Steel (TP304/TP304L ,TP316/TP316L), Alloy Steel (T11/T22) not limited
Fins Materials: Carbon Steel, Stainless Steel(TP304/TP304L,TP316/TP316L, TP409/TP410) not limited
Longitudinal Finned Tube typical sizes:
Bare tube size: OD 19.05mm-OD60mm
Fin number: 2/ 4/ 8/ 16/ 18/ 32/ 36 piece per row
