Abstract: A method for joining a first conduit section having a longitudinally extending open first end and an inner surface with a second conduit section having a longitudinally extending end and an outer surface is provided. The method comprises: a) inserting a first end of the second conduit section in the open first end of the first conduit section and forming a fluid tight seal between the first and second conduit sections; and, b) bonding at least a portion of the inner surface of the first conduit section to at least a portion of the outer surface of the second conduit section.

Abstract: A coupling for securing pipe elements together in end-to-end relation is disclosed. The coupling has segments joined end-to-end by adjustable connection members. The segments surround a central space which receives the pipe elements. One or more gripping bodies are captured between the segments. The gripping bodies are arranged opposite to each other. The segments have angularly oriented reaction surfaces on the connection members. The gripping bodies have angularly oriented contact surfaces which interface with the reaction surfaces. When the segments are drawn toward each other by the connection members, interaction between the reaction surfaces and the contact surfaces forces the gripping bodies radially inwardly. Inwardly facing arcuate surfaces on the segments and the gripping bodies engage and retain the pipe elements.

Abstract: A pipe joint is provided that effectively accommodates a relative positional displacement between pipes, thereby allowing unfailing coupling between the pipes. The pipe joint is provided with a flexible pipe main body in a circular cylindrical shape; a pair of flanges that is provided on both ends the pipe main body, and are coupled to end portions of the first pipe and the second pipe that face each other; and a plurality of string members that couple the flanges. Each string member includes a string main body and a pair of stopping members that are provided on both ends of the string main body with a predetermined distance, and the flanges are formed in an annular shape and include a plurality of flange pieces that are separately formed, an ear portion having a coupling hole for coupling the flange pieces, a coupling bolt that couples the flange pieces, and the application bolt that couples the first pipe and the second pipe.
