Abstract

A multi-layer tube is produced by introducing a tube into the interior of an outer tube. With an expansion device set into the inner tube with a hydraulically expandable hose (11) the inner tube expands plastically to contact with the outer tube and the outer tube stretches elastically. When the hose (11) is removed, the tubes form a shrink bond.<IMAGE>
