Abstract
A tube and end plug assembly include a tube having an inner diameter and an outer diameter; an end plug having a tapered body portion with minimum and maximum diameters and a radial flange adjacent the minimum diameter. The tapered body portion is located within an end portion of the tube which is in substantially continuous engagement with the tapered body portion of the plug. A related process of joining an end plug to a hollow tube having a cylindrical end portion, with inside and outside diameters, and wherein the end plug has a body portion with minimum and maximum diameters connected by a tapered surface and a radial flange adjacent the minimum diameter includes the steps of: a) inserting the end plug into the cylindrical end portion of the tube such that the radial flange engages an edge of the cylindrical end portion of the tube; b) deforming the cylindrical end portion of the tube into conformance with the tapered body portion of the end plug; and c) welding the end plug to the tube circumferentially about a joint between the radial flange and the edge.
