Abstract
A raised pipeline sleeve for a pipeline includes a tubular sleeve body insertable into pipeline pipes. Recessed sleeve shoulders are radially positioned about each end of the tubular sleeve body with a central portion therebetween. An outer surface of the tubular sleeve body along the central portion is shaped to conform to an inner surface of the pipeline pipes. The recessed sleeve shoulders are recessed a distance radially below the central portion to support a pipeline seal between the recessed sleeve shoulders and the pipeline pipes. A raised hump extends radially from the central portion along the outer surface of the tubular sleeve body. As the tubular sleeve body is inserted in the pipeline pipes, the pipeline pipes engage the raised hump and conform the raised hump to the inner surface of the pipeline pipes whereby installation of the tubular sleeve body into and alignment of the tubular sleeve body about the pipeline pipes is facilitated.
