Abstract
A heat exchanger includes a shell. A tubesheet is mounted to the shell. A plurality of tubes extend from the tubesheet and into the shell for heat exchange between a first fluid within the tubes and a second fluid in the shell outside the tubes. The tubesheet divides an interior of the shell into a heat exchange chamber where the tubes can exchange heat with the second fluid, an inlet-outlet chamber for the first fluid to enter and exit the tubes. A breech lock locks the tubesheet within the shell. A bi-directionally self-energizing gasket is seated between the tubesheet and the shell to seal the heat exchange chamber from the inlet-outlet chamber. The gasket is configured to be self-energizing to seal regardless of whether there is a higher pressure in the heat exchange chamber or in the inlet-outlet chamber.
