Abstract

A weld connection joining abutted ends of pipe (202, 204) includes a heat limiting sleeve (200) therein which provides a continuous seal to protect the weld and the interior portions of the pipe (202, 204) from the materials passing through the pipe (202, 204). The sleeve (200) may be configured from a non-metallic material, such as PTFE, and a plurality of seal rings (50, 52) may be located on the outer circumference thereof to seal the sleeve (200) to the interior surface of the pipe (202, 204). The non-metallic sleeve (200) is inherently non-corrosive, and therefore no secondary protective coatings need be provided on the interior surfaces of the pipe connection to protect the weld. To position the sleeve (200) in the pipe ends (202, 204), and to properly position the pipe ends (202, 204) for welding, the sleeve (200) includes a plurality of removable spacer pins (30) thereon which are removed from the sleeve (200) before the weld connection is completed.
