Tube To Tubesheet Joint

TUBE EXPANSION ISSUES AND METHODS - Haskel
By expanding the tube inside the tubesheet, swaging ensures that the space between the two components is always forced closed. Hydraulic expansion is the direct application of high internal pressure within a tube or sleeve in order to form a tight joint between the tube and tube sheet or a tight seal between the sleeve and tube. ...
