Abstract
An inline pipeline expansion joint is provided having a first sleeve with the outer end adaptable to attach to a pipe. A second sleeve also has an outer end adaptable to attach the attachment of a pipe, the inner end of the first sleeve being co-axially and telescopically received within the second sleeve. A seal is interposed between the interior of the first sleeve and the exterior of the second sleeve. A tubular liner is positioned within the second sleeve, one end of the liner being telescopically received within the interior of the first sleeve to thereby reduce turbulence of fluid flow through the expansion joint. The first sleeve has an external annular circumferential flange with openings therethrough that receive circumferentially spaced alignment rods that are secured at one end to the second sleeve so that as the first sleeve moves telescopically with respect to the second sleeve, the two sleeves are prevented from rotating with respect to each other.
