Abstract (en)
[origin: ES8301128A1] A tube end received in a bore of a tube sheet is expanded by introducing a mandrel into the tube end and utilizing fluid pressure to bias a pair of sealing rings outwardly to engagement with a tube end, thereby sealing off the clearance between the mandrel and the tube end. In addition to utilizing the fluid pressure to provide the sealing action, the invention admits the fluid pressure into the clearance and thereby expands the tube end.
