Abstract
A tube expander of the roller and mandrel type for expanding tubes within tube sheets having a housing assembly which includes a bearing mounted stop collar having a plurality of load-absorbing fingers provided with arcuate faces for limiting the axial position assumed by the tube relative to the tube sheet during the expansion of the tube. The arrangment includes a provision for predimensioning the portion of the tube which is ultimately to be exposed from the tube sheet whereby spacer members of selected thicknesses may be removed and installed on site.
