Improvements in the technique of sliplining a buried pipe, so as to minimize adverse affects of differences in expansion and contraction of the old and new pipe, while maintaining seals at the ends thereof is disclosed employing at each pipe end a sleeve-like pliable gasket, which is expanded outwardly into contact with the inner surface of the old pipe, and somewhat beyond the end of the old pipe, is contracted inwardly into contact with the other surface of the new or sliplined pipe. The sleeve-like gasket can compensate for thermally induced pipe line...


An arrangement for providing substantially liquidtight seals between a pair of nested generally coaxial elongated pipes near the respective pipe ends while allowing limited relative axial motion of the pipes as might occur due to temperature changes and dissimilar coefficients of thermal expansion for the pipes comprising: an outer pipe; an inner pipe axially extending in said inner pipe; said inner and outer pipes having dissimilar coefficients of thermal expansion; a pair of pliable sleeve-like gaskets having an outer circumference near one end approxi...
