ABSTRACT:
A shrouded fluid-conducting apparatus is provided that includes at least one outer conduit and at least one inner conduit disposed within the outer conduit. Preferably, the shrouded fluid-conducting apparatus further includes at least one shrouded end fitting disposed at an end of the shrouded fluid-conducting apparatus and at least one support member engaged with the inner and outer conduits. The shrouded end fitting allows the shrouded fluid-conducting apparatus to be engaged with an additional shrouded fluid-conducting apparatus. The support member allows for the transfer of loads from the inner and/or outer conduits to one or more components external to the shrouded fluid-conducting apparatus. Accordingly, the shrouded-fluid conducting apparatus may be used to transport fuel through an aircraft “ignition zone” in an FAA-compliant manner.
