Title:
管継手用ストップアセンブリ
Document Type and Number:
Japanese Patent JP2009506275
Kind Code:
A
Abstract:
A method for assembling a pipe coupling and a method of joining pipe elements in end to end relation using the pre-assembled pipe coupling. The pipe coupling is formed of segments joined end to end by fasteners. Retention elements positioned on the fasteners hold the segments in spaced apart relation. The retention elements have a first surface that engages the fastener and a second surface that engages the segment to inhibit the motion of the segments relative to the fasteners. The method includes engaging the fasteners with the segments and engaging the retention elements with the fasteners and the segments to position and hold the segments in spaced apart relation. Pipe elements are inserted between the segments and force is applied to the segments which overcomes the resistance of the retention elements to move the segments into engagement with the pipe elements.
