A fluid carrying arrangement 10 comprises an inner conduit 12 for carrying a first fluid 12A, and an outer conduit 14 for carrying a second fluid 14A. The inner and outer conduits 12, 14 are formed integrally and contemporaneously with each other. Preferably, at least one connecting member 20 for spacing the inner conduit 12 from the outer conduit 14 is also formed alongside the conduits. The connecting member(s) may extend axially along the length of the fluid carrying arrangement (as shown), or may comprise at least one strut member, which may be present in an array. The Fluid carrying arrangement is preferably manufactured from a sintered and/or melted metallic powder using a solid freeform fabrication process, e.g. selective laser or electron beam sintering and/or melting. |
