    • A coupling for joining pipe elements in end to end relation is disclosed. The coupling includes interconnectable coupling segments having connection members at opposite ends. The connection members are tightenable for drawing the segments toward one another and into engagement with the pipe elements. Each segment has a concavity positioned between inwardly projecting arcuate surfaces that engage grooves in the pipe elements. The concavities house a sealing member that extends circumferentially around the pipe elements. Angularly oriented surfaces are positioned adjacent to the connection members. The surfaces on facing segments engage one another and cause the segments to rotate in opposite directions about an axis perpendicular to the pipe elements. The concavities are angularly oriented with respect to the axis so that when the segments rotate, the cavities receive the sealing member without distorting it. A method of joining pipe elements end to end is also disclosed.
    • 公开了一种用于以端对端关系连接管元件的联接器。 联接器包括在相对端具有连接构件的可互连联接段。 连接构件是可收紧的,用于将段拉向彼此并与管道元件接合。 每个段具有定位在接合管元件中的槽的向内突出的弧形表面之间的凹陷。 凹部容纳围绕管元件周向延伸的密封构件。 角度方向的表面邻近连接构件定位。 相对的区段上的表面彼此接合并且使得区段围绕垂直于管道元件的轴在相反的方向上旋转。 凹部相对于轴线成角度地定向,使得当片段旋转时,空腔容纳密封构件而不使其变形。 还公开了一种将管元件端对端连接的方法。
