Longitudinal Finned Tube For Heat Exchangers

Longitudinal I/L or U-finned tubes are made with resistance welded fins along the length of the tube. The fins are first formed into a U-shaped channel so that each side of the U forms a fin. The channel is cut to the appropriate length, then oriented and resistance welded along the length of the tube. The channels are welded in pairs, diametrically opposed, so the number of fins specified must be a multiple of 4.

For a given tube or pipe size, the required heat transfer surface area per unit length of tube can be obtained by specifying the appropriate fin height and number of fins. The number of fins depends on the outside diameter of the tube – larger outside diameter tubes can accommodate more fins.
