<p>PIPELINE SLEEVE GASKET CONFINING STRUCTURE Elastomer seal rings are confined against their leakage or extrusion from a sleeve joining two segments of pipe or from a repair clamp placed at an end of such a sleeve which is leaking liquid from the pipeline by providing, in one embodiment, several segmented, triangularly shaped split rings which are overlapped at their ends to fit against and to coact with a beveled face within or at the end of a sleeve to retain packing rings at that end against pressure being exerted by a compression ring pressing against the packing from its opposite end. To avoid extrusion of the packing at the compression ring end thereof complementary essentially triangularly shaped split rings are provided or alternately a pair of rectangular split rings are provided one of which is of an internal diameter to fit snugly over the pipeline when snapped thereonto and the other of which has an outside diameter to fit snugly agianst the inner wall of the sleeve or repair clamp.</p> |
