Abstract
Apparatus for expanding a tube into a bore formed in a tube sheet in which a tubular force-transmitting member extends within the tube coextensive with the portion of the tube to be expanded. An explosive is disposed in the bore of the force-transmitting member, so that the forces resulting from the explosion of the explosive are uniformly transferred by the force-transmitting member to expand the tube into the bore. A tubular barrier member extends between the force-transmitting member and the tube and has a portion projecting from the tube sheet, and a plug is disposed in the end of the projecting portion of the barrier member to contain the debris and gases resulting from the explosion.
