Abstract
A method for joining pipe elements end-to-end using a pair of pipe couplings attached to one another end to end surrounding a central space includes inserting the pipe elements into the central space, moving the coupling segments toward one another and engaging surface regions of the coupling segments with outer surfaces of the pipe elements, initially at a first contact point on the coupling segments and subsequently at second and third contact points on the coupling segments. The first contact point is located between opposite ends of the coupling segments and may be located on a region of infinite radius of curvature, may project radially inwardly toward the pipe elements, and may be located midway between the opposite ends of the segments. The second and third contact points are located at opposite ends of the coupling segments.
