1. A raised pipeline sleeve for sealing pipeline pipes of a pipeline, the raised pipeline sleeve comprising:
a tubular sleeve body insertable into the pipeline pipes, recessed sleeve shoulders 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 shaped to conform to an inner surface of the pipeline pipes, the recessed sleeve shoulders being 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 extending radially from the central portion along the outer surface of the tubular sleeve body;
wherein, 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;
wherein each of the recessed sleeve shoulders comprises a rim and a recess, the recess positioned between the rim and the central portion.
