ABSTRACT:
A double containment pipe joint assembly is provided with an inner pipe and an outer or containment pipe secured in concentric relation. The pipe joint assembly includes a fitting having end surfaces on concentric flanges which can be secured to a length of a primary and containment pipe at intervals along the pipeline wherein sections of the pipeline can be removed and repaired without the necessity of removing the whole pipeline. The concentric flanges are joined by a thickened divider ring which provides smooth fillets at its juncture with the flanges to reduce thermal stresses on the fitting.
