Abstract
A method and apparatus for maintaining the pressure in an overclad tube at a reduced level despite axial movement of the tube during performance of an RIT overcladding operation. The overcladding tube is held by means of the lathe chuck, and a tubular extension of a rotary union member extends into the tube. The distal end of the extension has a sealing member replaceably mounted thereon which forms a seal with the interior wall of the tube. A vacuum source thus is enabled to connect to the interior of the overcladding tube through the rotary union, the extension tube, and the seal.
