Abstract: A tube assembly is additive manufactured as one unitary piece and has a first tube that co-extends with and is surrounded by a second tube. An annular void may be defined by and located between the first and second tubes for insulating a fluid flowing through the first tube. The void may be sealed and under a negative atmospheric pressure for enhancing insulating properties.

Abstract: A shrouded conduit is provided for arranging, for example, in a gas path of a turbine engine. The shrouded conduit includes a tubular shroud extending longitudinally along a centerline. The shrouded conduit also includes a fluid conduit extending longitudinally in the shroud. A first portion of the fluid conduit is connected laterally to and may be formed integral with a first portion of the shroud.
