U Bend Tube Application
U tube heat exchangers designed for high temperature applications, especially steam condensing or hot oil systems.
Application: Boiler, heat exchanger, super heater, feedwater heater, condenser. Thïs model is selected when differential
expansion makes a fixed tube sheet exchanger unsuitable and when conditions preclude a floating head type (HPF) selection.
