LONGITUDINAL FINNED TUBE
Longitudinal finned tubes are produced by welding fins with resistors along the length of the tube. The fins are first formed into a U-shaped channel, allowing each U-shaped leg to form a fin. The channel is cut to the appropriate length and then welded in place along the length of the tube and resistors. The channels are welded in pairs, at opposite poles, so the number of fins specified must be a multiple of four. For a given tube or tube 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.
