A method for preparing a multi-layer tube, useful prior to endforming for brakeline connections, comprises the steps of forming a metal tube having an outer surface and an end and bonding a corrosion resistant layer to the metal tube outer surface. A surface treatment layer is bonded to the corrosio
A method for preparing a multi-layer tube, useful prior to endforming for brakeline connections, comprises the steps of forming a metal tube having an outer surface and an end and bonding a corrosion resistant layer to the metal tube outer surface. A surface treatment layer is bonded to the corrosion resistant layer. A first polymeric layer is extruded onto the metal tube, such that is bonds to the surface treatment layer; and a second polymeric layer is extruded onto the metal tube, such that it bonds to the first polymeric layer. The method further comprises the step of vaporizing and removing at least a portion of the first and second polymeric layers from an area adjacent the end by rotating an axially defocused, generally elliptical cross-sectionally shaped laser beam 360° about the area, while leaving the corrosion resistant layer intact.
