    摘要： A mechanical pipe coupling is formed of segments attached end to end to surround a central space. Each segment has a circumferentially extending cavity facing the central space flanked by arcuate keys which project toward the central space. Two arcuate shoulder surfaces are positioned on each segment. The arcuate shoulder surfaces face the central space and are positioned in spaced relation on opposite sides of the cavity between the cavity and the arcuate keys. The arcuate shoulder surfaces are angularly oriented with respect to an axis perpendicular to a plane containing the segments. The coupling is used to couple pipe elements having a circumferential ring located at the ends of the pipe elements. The angular orientation of the arcuate shoulder surfaces provides flexibility to the joint. A method of joining pipe elements having circumferential rings is also disclosed.

    摘要： A mechanical pipe coupling is formed of segments attached end to end to surround a central space. Each segment has arcuate keys which project toward the central space. Each key is formed of a pair of side surfaces and a mid surface between them. The mid surface is angularly oriented relative to a longitudinal axis perpendicular to a plane containing the segments. When used to couple pipe elements having grooves the angular orientation of the mid surfaces provides flexibility to the joint. A method of joining pipe elements end to end is also disclosed.

    摘要： Mechanical pipe couplings for joining large diameter pipe elements in end to end relation have arcuate keys which engage circumferential grooves in the pipe elements and radially projecting stiffening ribs aligned with the keys. Key surfaces have angular orientations between 5° and 30°. At the end of the keys on opposite sides are camming surfaces which are formed by a thinning of the key. The camming surfaces may be concave, convex, or angularly oriented surfaces and serve to guide the keys into grooves when the keys are not directly aligned with the grooves.
