U tube heat exchanger is suitable for the large temperature difference between tube side and shell side. The shell side media is easy to scale and needs cleaning, while the tube side media is clean and not easy to scale. It is also suitable for high temperature, high pressure, fluid corrosive working conditions.
Each heat exchange tube is bent into U-shape, the two ends are fixed in the upper and lower areas of the same Tube Sheet, and divided into two chambers of inlet and outlet with the partition in the tube box. This kind of heat exchanger completely eliminates the thermal stress, the structure is simpler than the floating type, but the tube side is not easy to clean.
The number of tubes is small, the utilization of the tube sheet is not frequent, and the shell side fluid is easy to short circuiting, which is unfavorable to heat transfer. If there is a leak or damage in the tube, the external U-tube can be replaced, while the broken inner tube can not be replaced, only plugged, and one broken U-tube means two broken, so the U-tube easily scrapped.
