A fluid carrying arrangement 10 comprises an inner layer 12 for carrying the fluid, and an outer layer 14 around the inner layer, the outer layer being formed integrally with the inner layer. The fluid carrying arrangement 10 is preferably made from a metal powder material, and manufactured by a solid freeform fabrication process such as selective laser or electron beam sintering or melting. The outer layer 14 preferably comprises an insulating layer. The insulating layer may comprise an insulation carrier capable of carrying insulating material (e.g. ceramic), and may be porous. |
