Abstract:
A process for operationally attaching a cylindrical fluid--flow-conducting tube to a heat exchanger having generally cylindrical fluid inflow and outflow sleeves operatively connected to fluid inflow and outflow tank portions thereof comprising the steps of:a). establishing a positive stop that radially extends from a predetermined position on a first of said sleeves,b). placing an annular constricting and locking ring on said flow conducting tube to be connected to said first of said sleeves;c) telescoping the end of said flow conducting tube into said first of said sleeves;d) applying a force to and thereby displacing said constricting and locking ring from a position on said flow conducting tube to a predetermined position around said first of said sleeves as established by physical contact of said constricting and locking ring with said positive stop; and thereby effecting the annular constriction of said first of said sleeves onto the telescoped end of said tube to permanently establish an annular fluid seal between the telescoped end of said tube and said first of said sleeves located radially inward of and in alignment with said locking ring.
