Abstract
The tube sheet of a heat exchanger supports a plurality of tubes made from a material such as titanium. A shield is provided for the tube sheet and is welded to the tubes. The shield is made from the same material as the tubes and is spaced from the tube sheet to define a fluid chamber containing fluid at a pressure in excess of the pressure of the liquid flowing through the tubes.
