    Abstract: Described is a tubing assembly which includes a permanently deformable outer tube, an intermediate tube and an inner tube. A radial seal is provided by a uniform radial crimp having a non-zero longitudinal length at a longitudinal location on the tubing assembly. In some embodiments one or both ends of the assembly have a uniform radial crimp and are polished so that the ends of two or more of the tubes are substantially flush with each other to thereby block the passage of fluids between the ends of the tubes. In other embodiments the uniform radial crimps are at other longitudinal locations where a high pressure seal is desired. The longitudinal length and the depth of each uniform radial crimp can be formed to accommodate the requirements of a particular application so that leakage along the tubing assembly is prevented and void volume is reduced or eliminated.

  • Patent number: 8651148
    Abstract: This invention relates to a pipeline assembly especially for offshore installation comprising an inner carrier pipe, a casing and at least one closed-cell and/or solid thermal insulation material layer placed in between the casing and the inner carrier pipe, and the at least one insulation layer being directly or indirectly bonded to at least the casing and the inner carrier pipe. The pipeline assembly has improved bending properties which is achieved as the insulation material layer comprises at least one slit substantially transversely to the longitudinal direction of the pipeline assembly. The slit can be applied as a helical or circumferential cut, enabling the pipeline assembly to be rolled onto a reel or spool which greatly improves the pipeline assembly installation process. Methods of improving the bending properties of such a pipeline assembly are also described.

  • Publication number: 20140020785
    Abstract: An exhaust-gas conducting device of a vehicle has a cylindrical outer housing which is comprised of an outer shell and an inner shell arranged in an interior of the outer shell. The outer shell forms a larger portion of an outer circumference than the inner shell, or forms an equally large outer circumferential portion. A radial outside of the inner shell is attached to the outer shell, in particular by a material-to-material connection. The outer shell is C-shaped in cross-section, or extends in an annularly closed manner.

  • Patent number: 8616246
    Abstract: The invention provides an insulated pipe-in-pipe assembly comprising (a) at least one inner pipe, (b) an outer pipe disposed around the at least one inner pipe so as to create an annular space between the outer and inner pipes, (c) porous, resilient, compressible material disposed in the annular space, and (d) a remnant of a container that previously was positioned in the annular space and previously held the compressible material in a volume less than the volume of the compressible material in the annular space. The invention also provides a method for making such an insulated pipe-in-pipe assembly.

  • Publication number: 20130312865
    Abstract: A double-wall pipe for a transportation means which includes an outer pipe and an inner pipe extending therein. The outer pipe has two pipe segments which are formed like half-shells and are joined together to form the outer pipe along the longitudinal edges thereof. In this way, it is possible to make both the outer pipe and the inner pipe of metal, such that the wall thickness of the inner pipe can be relatively small.

  • Patent number: 8555930
    Abstract: An assembly of at least two coaxial pipes having at least two coaxial pipe assembly unit elements, one of which has, at one end, a first junction part assembled to a second junction part at the end of another said coaxial pipe assembly unit element, each of said first and second junction parts being a body of revolution, wherein the ends of the two non-welded-together inner second branches of said first and second junction parts are in metal-on-metal contact one on the other under elastic deformation stress via their contact surface as a result of the shrinking of the weld between the ends of the two outer second branches of the junction parts, such that the inner second cavities are leaktight relative to the inside of the inner pipe.

  • Publication number: 20130126034
    Abstract: A vehicle exhaust system includes a subsystem having an exterior pipe formed of a polymer. A rigid liner extends along the length of the exterior pipe and defines a passageway. A fiber insulating layer is formed between the rigid liner and the exterior pipe. The liner is formed to define at least one groove circumscribing the periphery of the passage-way. The groove defines a region of increased volume of the exhaust passage along the length. The liner is further formed to define at least one void extending between the wall of the liner and the insulating layer, around the periphery of the passageway. A plurality of apertures in the liner, allow sound waves to pass from the passageway into the fiber insulating layer, and into the void.
