ABSTRACT:
Joint and joint components designed to withstand axial compressive loads join a pair of pipe sections end-to-end, the adjacent ends of the sections being threaded. A coupling member for connecting the threaded adjacent ends of the pipe sections includes threads interengaged with the threads on the adjacent ends of the pipe sections. An abutment member located between the outer ends of the pipe sections is shaped so that the ends of the pipe sections abut against opposite sides of the abutment member. Each pipe section includes a shoulder which is formed integral with and extends circumferentially around the section, the shoulder including an angled surface which faces the angled surface on the other pipe section and is oriented at an angle substantially the same as the surfce on the other pipe section, each surface terminating at a circumferential edge which is closer to the edge on the other pipe section than is any other portion of its respective surface. One of the coupling and abutment members includes angled surfaces which approach being complementary to and engaging the surfaces on the pipe sections when the joint is formed and a compressive load is applied, whereby the angled surfaces enhance the load bearing surface area of the pipe sections so that when they are subjected to an axial compression load deformation of the sections is retarded.
