摘要： 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.

摘要： A concave bearing surface for use with lugs of pipe coupling segments is disclosed. The concave bearing surface is positioned on the lug and surrounds an aperture which receives a fastener attaching the coupling segments together end to end surrounding pipe ends to be joined. Either the nut or the head of the fastener that engages the concave surface may be rotated to tighten the fastener. Engagement between the concave surface and the rotating member reduces the torque required to tighten the fastener and effect a stiff, fluid tight joint. A method of securing pipe ends using coupling segments with concave bearing surfaces is also disclosed.
摘要翻译：公开了一种用于管接头段的凸耳的凹面支承面。凹入的支承表面定位在凸耳上并且包围一个孔口，该孔口接收将连接段连接在一起的端部围绕要连接的管道端部的紧固件。接合凹面的紧固件的螺母或头部可以旋转以紧固紧固件。凹面与旋转构件之间的接合减小了紧固紧固件所需的扭矩，并实现了刚性的流体密封接头。还公开了一种使用具有凹形支承表面的联接段固定管端的方法。
