Coupling members for pipeline assemblies

In combination, a coupling member assembly comprising plural coupling member sections formed from a material of high mechanical strength and which have complementary longitudinally extending faces permitted assembly of the coupling member sections into a unitary coupling member having a central passage, first extensions of said coupling member sections at each of the ends of said central passage, said first extensions each defining a gasket housing portion, second extensions of said coupling member sections contiguous with said first extensions, said second extensions each defining a pipe clamping element, a conduit member positioned within said central passage, said conduit member being formed from a mechanically weak and relatively inexpensive material having high resistance to abrasion or attrition by abrasive particulate material, ends of said conduit member located within said first extensions, and gasket members positioned within said first extensions and sealingly engaged with said conduit member ends.

A quick-connect and disconnect coupling for conduits, particularly for conduits used for conveying particulate abrasive material entrained in a fluid medium, said coupling being comprised by separable rigid coupling member halves having cooperating axially extending faces, said coupling member halves defining a central passage and defining a gasket housing at each of the ends of said central passage and further defining pipe clamping members formed by extensions of said coupling member halves at each end of said central passage, detachable means securing said respective coupling member halves to each other in rigidly assembled relationship, a conduit member formed of an abrasion resistant plastics materials contained within said rigid coupling member halves and which has an exterior surface contacted and supported by said rigid coupling member halves throughout substantially the entire extent of the outer surface of said conduit member, and, gasket members contained within said gasket housing portions and engaged with said conduit in sealing relationship therewith.
