A U Tube Heat Exchanger is a type of shell and tube heat exchanger where the tubes are bent in a U-shape and fixed to a single tubesheet. This design allows for thermal expansion, easy maintenance, and efficient handling of high-temperature and high-pressure applications in industries like oil, gas, chemical, and power. https://www.unitedheatexchangers.com/heat-exchanger/U-Tube-Heat-Exchanger/
