Abstract
A closure for a heat exchanger of the shell and tube type in which fluid under high pressure is circulated through one or more tubes mounted in the shell. The pressure of the fluid flowing through the shell is lower than the pressure of the fluid in the tubes. The closure includes a single seal member for sealing between the tube sheet and the shell terminal member and between the tube sheet and the closure member and between the terminal member and the closure member. The tubes are bent in a hairpin shape with a separate closure at each end of the tubes. An opening in the end of the shell allows the tube and tube sheet to be inserted into and removed from the interior of the shell.
