Some heat exchanger advertises the availability of finned tubes in a hairpin or double pipe heat exchanger. These would always be longitudinal fins, rather than the more common radial fins used in a cross-flow finned tube heat exchanger. In a double pipe heat exchanger design, an important factor is the type of flow pattern in the heat exchanger.

Taking the heat transfer coefficient inside the pipe to be h1 = 60 W/m2K, determine the rate of heat loss from the steam per unit length of the pipe. Also determine the temperature drop across the pipe shell and the insulation. Assumptions: Steady‐state and one‐dimensional heat transfer. Solution:
exchangers if the available space is a limiting factor, if the heat exchanger surfaces have to be cleaned, or if the heat exchanger shape is restricted by special geometric constraints. If these conditions do not apply, plate-fin tube heat exchangers are preferred because of their lower production costs per heat exchanger area [10].
