Heater core set - U-tube structure - petrochemical - steam and oil
The U-tube heat exchanger has fewer tube sheets than the fixed tube sheet heat exchanger, and its leakage points are correspondingly reduced. In addition, it is also easier to dry after the shell-side hydraulic test of the U-tube heat exchanger, and it has a wide range of applications, simple maintenance and good operation flexibility. If the heat exchange area of the heat exchanger is small, the temperature difference between the shell side and the tube side is large, or the medium on the shell side is easily dirty, and the surface of the tube bundle needs to be cleaned frequently, U-shaped tube heat exchangers are generally used.
