Abstract
A threaded joint () provides for metal-to-metal sealing on the ends of concentrically positioned inner and outer tubes when joining the concentric tubes to a single tube (). A threaded coupling () secures the inner and outer tubes and joins both tubes to a single tube. The threaded connection leverages metal-to-metal sealing on the ends of each tube. The inner tube () may differ in length from the outer tube () and contains a single thread () at its for receiving the threaded coupling. Threading the coupling onto the inner tube establishes four flexing metal-to-metal seals (A-D) between the threaded joint components. The inner and outer tubes maintain contact at the internal shoulder () as a result of preloading. If the tubes are of varying thicknesses, a nut () is placed between the internal shoulder and the threaded coupling to preserve contact between the tubes at the internal shoulder.
