Claim 17:
18. A process for assembling a tube heat exchanger assembly comprising:
providing an elongated heat exchanger enclosure having an interior chamber and defining a longitudinal axis and having an open cylindrical channel end;
providing a closure assembly having a locking assembly configured to secure to the open cylindrical channel end of the elongated heat exchanger enclosure;
inserting the locking assembly of the closure assembly into the open cylindrical channel end axially along the longitudinal axis of the interior chamber of the heat exchanger such that load bearing surfaces of each of the closure assembly and an interior wall of the elongated heat exchanger enclosure do not contact one another;
turning the closure assembly about the longitudinal axis of the elongated heat exchanger enclosure less than 360 degrees relative to the elongated heat exchanger enclosure to cause the locking assembly to removably secure to a cooperating locking assembly provided on the interior wall of the elongated heat exchanger enclosure to cause the load bearing surfaces to contact one another such that a load is transferred between the closure assembly and the elongated heat exchanger: and
wherein turning the closure assembly includes causing spaced-apart lock ring hub sections of the closure assembly to interdigitate with corresponding channel hub sections of the cooperating locking assembly of the elongated heat exchanger enclosure.
