    摘要： Coupling (10) for joining pipe elements, said coupling comprising: a plurality of segments (12, 14) attached to one another end (22, 24) to end surrounding a central space (16) for receiving said pipe elements, each of said segments comprising: at least a first channel (54) positioned on a first side of said segments, said first channel (54) extending between said ends of said segments (12, 14); a first aperture (42) in at least one of said segments (12, 14), said first aperture (42) providing a line of sight (44) toward said central space (16).

    摘要： A coupling installed by crimping has an angularly oriented conical surface at an open end surrounded by a ring which receives a pipe element. Dies move radially toward the coupling on jaws of a crimping tool and engage the conical surface along a single line of contact to effect a crimp which secures the coupling to the pipe. The radially applied force has radial and axial components. The radial component effects the crimp, the axial component deforms a channel in the coupling in which a seal is located. The seal is deformed between the coupling and the pipe to effect a fluid tight joint. The coupling may have a circumferential rib which projects radially outwardly. Registration dogs engage the coupling and provide a reaction surface against the axial force component.

    摘要： A fitting has a conduit with a bore defined by a surface facing an axis coaxially located with respect to the bore. The surface may have three portions including a conical portion located proximate to the inlet of the conduit, a threaded portion located proximate to the outlet of the conduit and a cylindrical portion located between the conical and threaded portions. A gasket is positioned within the conduit. The gasket has an outer surface and an inner surface facing the axis. The gasket inner surface has angularly oriented lands. One of the lands faces the outlet and is engaged by a threaded component received by the threaded portion. Engagement between the component and the land compresses the gasket radially outwardly and longitudinally within the conduit. An angularly oriented shoulder guides the gasket into a redirection space defined by the conical portion (when present) as it deforms.

    摘要： A pipe element has a circumferential groove with a surface portion oriented at an angle with respect to its longitudinal axis. A surface portion of the groove adjacent to the angled surface portion is oriented perpendicular to the longitudinal axis. A mechanical coupling has projecting keys that engage the groove. The keys have mating surfaces that contact both the perpendicular and angled surface portions of the groove. When the pipe element and coupling are used in combination to form a pipe joint, axial load on the pipe, resisted by the mechanical coupling, is shared between the perpendicular and angled surface portions which results in a pipe joint that can withstand higher internal pressure than if the axial load were borne by the perpendicular surface portion alone.
