For the expansion ratio R(exp) of the pipe connection, the following applies: 0.05<R(exp)=[D(max)/D(internal)]?1<0.35 wherein D(max) stands for the maximum external diameter of the circumferential ribs and D(internal) for the internal diameter of the pipe.

Abstract: A duct replacement device and method of use provides a duct sleeve flex connector, in three different versions, each with a flat, rigid metal bar with thin, metal bracing strips and a female-treaded pole hinge. After cutting loose the old duct from under the register box, an HVAC technician enters the attic and threads the device on a telescoping pole, depositing the device near the open register box. The technician then climbs a ladder under the register box, grabs and adjusts the device with the flat, rigid metal bar into position, then attaches it with the thin, metal bracing strips.

Abstract: A threaded joint (200) 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 (107). A threaded coupling (105) 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 (102) may differ in length from the outer tube (101) and contains a single thread (211) at its for receiving the threaded coupling. Threading the coupling onto the inner tube establishes four flexing metal-to-metal seals (209A-D) between the threaded joint components. The inner and outer tubes maintain contact at the internal shoulder (104) as a result of preloading. If the tubes are of varying thicknesses, a nut (407) is placed between the internal shoulder and the threaded coupling to preserve contact between the tubes at the internal shoulder.
